Name the factors which help in changing the strength of an electromagnet.

$\huge \sf \red{ᴀnswer}$

The strength of an electromagnet depends on:-

The strength of the current passing through the coil, the greater the current, the greater the strength. This because the current increases there is more flow of electrons which in turn increases the magnetic field around it.

The number of turns in the coils, the greater the number of coils, the greater the strength. This is because more the number of coils, more uniformity is obtained in the magnetic field and hence it is more stronger.

Whether the core is made up of a soft or hard magnetic material. Soft iron core magnetizes more quickly than hard magnetic materials like steel.
