1. Magnetic Force: Definition, Poles & Dipoles

A magnetic force is produced when electrons are moving and many become magnets themselves. Discover more about magnetic forces, the root of magnetism, and monopoles and dipoles.

2. What is a Magnetic Field?

A magnetic field is created when magnets are in the same space as one another, creating a force. Learn more about a magnetic field, how to detect it with a compass, and ferromagnetic Materials.

3. How Magnetic Fields Are Created

Magnetic fields are generated when charged particles move around. Explore more about magnetic fields, their source, current carrying conductors, and electromagnets and how they act.

4. How Magnetic Forces Affect Moving Charges

A charged particle that moves through a magnetic field will be exposed to and affected by a particular force. Discover more about the effects of force on a moving charge, why relative motion is important, and the direction and strength of force.

5. Electromagnetic Induction: Definition & Variables that Affect Induction

Electromagnetic induction involves altering a magnetic field can produce a voltage and is utilized in many different applications. Explore more about electromagnetic induction, including its applications and the variables that affect induction.

6. Electromagnetic Induction: Conductor to Conductor & Transformers

Electromagnetic induction is the production of electromotive force by moving a magnetic field across an electric conductor. Learn more about mutual inductance, its applications, and transformers.
