What type of magnetism is generated when a current-carrying wire is wrapped around an iron core?

The correct answer is temporary magnetism.

Explanation:

Electromagnet is a temporary magnet. It has temporary magnetism. When an iron core is wrapped by using the current carrying wire. When current is switched off then it will lose its magnetism. If the current starts flowing in the wire then it will again gain its magnetism.

The strength of magnetic field  is proportional to the amount of current through the wire.

Therefore, the type of magnetism is temporary when a current carrying wire is wrapped around an iron core.

step-by-step explanation:

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
