MAGNETIC FIELDS
Electric and magnetic fields (EMFs) arise from the generation, transmission and
use of electricity. The result is that everyone today is exposed to a complex mix of
EMFs, both at home and work.
Magnetic fields are created when an electric current flows. Magnetic and electric
fields then exist together. The greater the current, the stronger the magnetic field.
Magnetic particle inspection involves the generation of magnetic fields to locate
defects in ferrous materials. It has been used for many years with no reported
health eects. Although an extremely useful and eective Non Destructive Testing
(NDT) method, there are growing concerns that exposure to EMFs could have
detrimental health eects.
There is very little conclusive information on the eects of exposure to intense
fields. However, research by various authorities has shown that, under certain
circumstances, acute exposure to intense fields of around 60 mT can result in
headaches and alterations in visual response.
The National Radiological Protection Board (NRPB) has developed guidelines to
protect people from these potential eects. No health risks have been established
for weak fields.
Typical magnetic field strengths for domestic appliances:
• Vacuum cleaners – 2-20 microtesla at 30 cm from the appliance
• Electric drills – 2-20 microtesla at 30 cm from the appliance
Typical magnetic field strengths for some Magnaflux MPI equipment:
• MAG 50 coil – 1.3 millitesla at 30 cm
• MAG 50 head/tailstock – 1.5 millitesla at 45 cm
• Y6 Yoke < 1 millitesla at 15 cm
Units of measurement for Magnetic Field Strength – tesla (T)
1 tesla = 1,000 millitesla (mT); 1 millitesla = 1,000 microtesla (µT)

METALLIC IMPLANTS AND MEDICAL ELECTRONIC DEVICES
Persons susceptible to strong magnetic fields, including those with pacemakers,
are advised not to use or approach this equipment without seeking professional
advice.
The NRPB advises that interference with the normal operation of medical electronic
devices may occur at levels of exposure to EMFs below the investigation level
(1.6 mT). In some circumstances, heating of metallic implants may occur. Advice on
acceptable exposure levels for people with metallic implants or medical electronic
devices, such as pacemakers, should be obtained from the manufacturers and
those responsible for implanting such devices.
GENERAL
The YM5 Recharger (Re-Magnetising) Fixture comprises a baseboard on which are
mounted one switch unit and two 8-turn coils. Supplied loose with this is a battery
charger, which operates at 220/240 V, 50 Hz and an extended keeper bar.
The YM5 Recharger is designed to run from one 12 V car battery, part number
Yuasa SWLL2250 (FR) or equivalent.
SETTING UP
Connect the appropriate leads to the terminals of the battery, greasing them well to
avoid corrosion. Charge the battery if not purchased locally fully charged.

OPERATION
• Ensure that the feet of the YM5 are in good condition and flat to make good
contact with the keeper bar
• Position the Yoke by placing each leg through a coil (as shown in the diagram),
ensuring that the feet protrude through to the other side. Place the extended
keeper bar across the exposed feet of the Yoke making sure good surface to
surface contact is made between the feet and the bar.
• Once the Yoke is in place, ensure that the red switch knob (PB1) is in the raised
position, then press the Green ‘Re-magnetise’ button (PB2) for no more than
one second, to re-magnetise the Yoke.
Note: During an emergency, or to prevent accidental operation, pressing the
red switch knob will break the main and auxiliary contacts, disconnecting the
coils and switch solenoid from the batteries.
• The Yoke can now be removed. To do this, slide the keeper bar o the Yoke’s
feet, rather than pulling it o. Remove the Yoke from the coils and immediately
reposition the Yoke legs. Fit the keeper bar that is supplied with the Yoke, not
the one from the Recharger.
A properly magnetised YM5 Yoke will lift a weight of 18 Kg suspended from the
pole faces (feet). A certified lift weight, part number 026T018, is available from
Magnaflux.
The YM5 Recharger re-magnetisation procedure may be carried out ten times from
fully charged batteries before the batteries will need re-charging. Use the supplied
battery charger to recharge the batteries. The batteries should be checked for acid
levels at weekly intervals.

YM5 PERMANENT MAGNET YOKE
The YM5 Yoke consists of hinged arms and rotating pole pieces to allow a wide
variety of profiles to be magnetised, whilst the specifically-shaped pole pieces
permit easy removal from the components. The elements of the YM5 are cast in
Magloy 1 for maximum magnetic field strength.
The YM5 is supplied with a keeper bar, which has false indications to enable you
to easily check the magnetisation strength.
Features:
• Field strength, with pole tips in contact: > 7,000 gauss
• Field strength in centre of 50 mm air gap:> 400 gauss
• Weight: 3 Kg
• Pull test: > 18 Kg (40 lb)

Treat sulphuric acid with respect. It is a highly corrosive liquid and will cause severe
injury if splashed on the skin or in the eyes, or if taken internally. It rapidly destroys
most clothing. Sulphuric acid is scheduled as a poison in Part 2 of the Poisons List.
Always:
• Wear acid-resistant clothing, goggles, PVC gloves and rubber boots
• Have a copious supply of water available
• Keep an eyewash bottle ready, containing 1% of saline solution
Take every precaution to avoid acid spillage:
• Handling: wear full protective clothing where there is a risk of splashes
• Spillage: wearing full protective clothing and working from the windward side,
wash down immediately with a copious supply of water, directing the water jet to
the outside of the spillage and carefully working towards the centre. Large
spillages should be contained with soda ash, sand or earth and gradually
neutralised with soda ash, finally washing down with water.
• Storage: use only approved vessels. Store them in a cool place away from
other chemicals, sunlight and hot pipes etc. Bungs on all containers should be
kept uppermost. Adequate ventilation in the building where the acid is stored
or handled is essential.
• Fire: sulphuric acid in contact with metals slowly generates hydrogen gas
which forms an explosive mixture with air. Naked lights should not be used in
or around road tankers, storage tanks or other containers of sulphuric acid.
FIRST AID
• Splashes in eyes: immediately irrigate the eye(s) for at least 15 minutes using l
arge amounts of water or, if available, saline solution. Obtain medical treatment.
• Splashes on skin: immediately remove contaminated clothing, taking care to
avoid self-contamination, and wash the aected parts with large quantities of
water. If symptoms occur, obtain medical treatment.
• Swallowed: drink copious quantities of lime water or milk of magnesia, or, alter-
natively, plain water and milk. Do not induce vomiting. Obtain medical attention,
preferably at a hospital, as soon as possible.
BATTERY HEALTH AND SAFETY
Subsequent charging
The charging current in amps should not be more than 10% of the battery’s rated
capacity in ampere hours (A/h), i.e. charge a 50 A/h battery at 5 amps. Before
gassing commences, the charging rate can be higher than this for short periods,
but in no case must the acid be hotter than +55°C. Observe the instructions of the
battery charger manufacturer.
After charging, check the acid level again and, if necessary, top up with distilled or
deionised water and fill to the acid level marking.
Maintenance
The new technology used in maintenance-free batteries means that, under normal
conditions of use, it should no longer be necessary to top up the battery with
distilled water. If overcharging occurs, it can become necessary to top up. In such
cases, it is advisable to check the acid level even on a maintenance-free battery.
Keep the battery clean and dry, and take care that the connections to the terminals
are firm and secures.
Storage
Before storing, the battery should be fully charged. Storage conditions: -20°C to + 50°C.
WARNING: The gases given o when charging are explosive
• No smoking or naked flames. Ensure that cables and electrical equipment are
handled in such a way as to avoid sparks.
• Before fitting or removing the batteries, make sure that all equipment connected
to it is switched o to avoid accidental sparking
• Take care that tools do not cause accidental short-circuits
• When charging, connect the battery to the charger before switching the charger
on. Reverse the process at the end of charging.
• When charging indoors ensure that there is adequate ventilation
