Answer 2

The factors affecting the strength of an electromagnet are:

1. Number of turns of the coil.

2. The amount of current flowing through the coil.

3. the presence of a core.

• The number of turns of a coil is directly proportional to the strength of a magnetic field. more the number of turns of the coil, the greater the strength of the magnetic field of the coil.
• There is a production of a strong magnetic field when the current flow is high.
• It is easier to magnetize softcore iron and it produces a strong magnetic field.
• The formula also gives the same information, B = μNI/L where "b" is the magnetic field, "N" is the number of turns of the coil, "I" is the current, and "L" is the length.
