Answer:
Charge on the sphere will be equal to
Explanation:
We have given radius of the sphere a = 13 cm
And electric filed 21 cm from the center is
So distance from the center r = 21 cm
We have to find the charge on the sphere
As
So according to Gauss law electric field is equal to
So
So charge on the sphere will be equal to
I think you're fishing for "temporary magnet" or something like that,
but I don't agree with it.
Credit card strips, refrigerator magnets, recording tape, bar magnets,
and big heavy horseshoe magnets are permanent magnets ... you don't
have to keep an electric current circulating around them to make them
magnetic.
But that doesn't mean that they stay magnetic no matter WHAT you do
to them. They can be DEmagnetized by being heated, dropped on the
floor, hit with a hammer, or in the presence of another, stronger magnet.
