Frank wants to convert an iron rod into a permanent magnet. He has a bar magnet and an iron rod with endsIandII,as shown in the given figure.
He wants endIof the rod to be the South Pole. He knows that by touch-stroke method, an ordinary iron bar can be changed into a permanent magnet.
Which figure represents the correct process that Frank should adopt to change endIof the iron rod into South Pole?
what is directive property of magnet
how are magnets used to attract big things like iron etc.?
what is the difference between magnetic force and electro-magnetic force?
How we can mention magnetic north and magnetic south pole of temporary magnet which is magnetised by bar magnet by single touch method?????
what is magnitite
1. What happend when 2 pins are attracted to a bar magnet and u bring aonther bar magnet to towards the pins
A) with the same pole B) with the opposite pole.
write me ur observation and state the reason pls.
2. Hold the first pin attaracted to the magnet and detach it from the magnet by holding it tight
a) what happend to the remaining pin.
b) what happend when the magnet is moved away.
c)How long does this effect remain ?
d) What do u infer ?
3.A note of any other observation of your inference ?
how is the single touch method of megnetism different from the double touch method
Take two identical iron pins and magnetize them by the touch and stroke method. Make sure that you are stroking both the pins with equal number of strokes so that they have the same strength as magnets. Now, take a small piece of thermocol and insert both the pins, as shown in the given figure. Place this piece in a small tub filled with water so that it can float. Gently rotate the piece in a particular direction and then observe its motion. Can you guess when this piece of thermocol will stop rotating?
