GCSE Physics - Electromagnetism #78

The video tutorial explains how electric currents generate magnetic fields, using the right hand rule to determine field direction. It covers the behavior of magnetic fields in wires, coils, solenoids, and electromagnets. The tutorial also discusses how to control and enhance the strength of electromagnets by adjusting current, coil turns, and adding an iron core.

What is the phenomenon that occurs when electric currents produce their own magnetic fields?

Explain the right hand rule and how it helps determine the direction of the magnetic field.

Describe how the magnetic field changes when the direction of the current in a wire is reversed.

What are the four ways to increase the strength of an electromagnet?

How does adding an iron core to a solenoid affect its magnetic field?
