Question

What happens when you increase the number of coils in an electromagnet

Answer 1

Answer:

refer to the attachment

Answer 2

When the number of coils is increased in an electromagnet and the following thing occurs:

• The strength of the electromagnet is directly proportional to the loops of the coil.
• Moreover, if we double the number of turns, the strength becomes double of the electromagnet.
• A greater number of coil turns results in a higher inductance and all other things being equal.
• However, when the coil's turns are reduced, the inductance also gets decreased.
• Also, the inductance increases with increasing wire turn in the coil and decreases with decreasing wire turn in the coil.
• Doubling the number of coils doubles the mmf, and by maintaining the same current and increasing the turns of the coil, magnetic field strength increases.
• It is because each loop of the coil sets up its own magnetic field.
