Question 1 of 5
What is the primary factor that determines the strength of an electromagnet?
Electromagnet strength is directly proportional to turns & current (Ampere-turns).
Question 2 of 5
Which material is typically used as the core of an electromagnet to enhance its magnetic field?
Soft iron has high permeability, concentrating magnetic flux better.
Question 3 of 5
What happens to the magnetic field of an electromagnet if the current flowing through its coil is reversed?
Reversing current flips the magnetic field's north and south poles.
Question 4 of 5
In an electromagnet, what is the role of the insulated wire coil?
Current flowing through the coil generates the magnetic field.
Question 5 of 5
Which of the following applications primarily utilizes electromagnets?
Relays and solenoids use electromagnets for switching and mechanical movement.
