Question

(a) draw the magnetic field lines of a bar magnet ."two magnetic field lines never intersect each other " .why?(b) an electric oven of 1.5kw is operated in a domestic circuit(220v) that has a current rating of 5A. what result do you expect in this case? explain

Answer 1

a) The magnetic field lines never intersect each other it it do so that means at the point of intersection. The magnetic compass will point in two directions which is impossible.

b) power=V *I
=220*5=1100w =1.1kw
Resistance=V/I
=220/5=44 ohm

Answer 2
