Question

Two electromagnet s are made by wrapping a
few turns of wire on similar nails and passing
the same amount of electric current through
them. The number of turn of the wire wrapped
over the two iron nails are in the ratio 2:1.
The strength of
(a) the first electromagnet will be
greater
(b) the second electromagnet will be
greater
(c) both the electromagnets will be
equal​
