Question

Arrange the strength of below electromagnets in ascending order based on number of coils and current flowing.

• A. 1000 coils, 70 A
• B. 10 coils, 20 A
• C. 10 coils, 30 A
• D. 10 coils, 10 A

Answer 1

As an electromagnet is technically a current carrying conductor, the magnetic field generated in it, can be amplified by increasing the turns of the coil or by increasing the flow of electric current through it. So, the higher the current through the coil, the more the strength of the electromagnet will be.
