Magnetic Fields
Consider a compass
Solenoids
Magnetic Forces on Wires and Charges
Parallel Current Carrying Wires
Moving Charges in Magnetic Fields
Motors
Electromagnetic Induction
Faraday discovered many ways to induce a current.
Another example of this comes when you move a bar magnet into or out of a hollow solenoid.
Transformers

Moving Charges in Magnetic Fields
In the same way that charged particles moving through a wire will experience a force in a magnetic field, so will free charged particles.
Magnetic force is always applied perpendicular to the direction of the charge’s motion.
To determine the direction of the force on such a particle we simply use the RHR.
