What are the two advantages of using electro-magnets to create a magnetic field?
Electro-Magnets
Electro-magnets are devices that create a magnetic field through the flow of electric current, typically consisting of a wire coil wrapped around a magnetic core, and are used in various applications including motors and relays.
Magnetic Field
An area surrounding a magnetic substance or an electric charge in motion where magnetic forces are experienced.
- Gain insight into the core principles and workings of electric induction motors.
- Clarify the significance of voltage and current in developing magnetic fields in induction motors.

Final Answer :
First, the strength of the magnetic field is controlled by the intensity of the current flow through the wire coil, and second, the magnetic pole polarity is reversed when the direction of current flow through the wire coil is reversed.
