Magnet

A material that produces a magnetic field, available in various shapes, sizes, and strengths.

Magnetic Field

A 3D field represented by lines leaving the North pole and entering the South pole, responsible for attracting ferromagnetic materials like iron.

Earth’s Magnetic Pole

The geographic North Pole acts as a magnetic South Pole.

Ferromagnets

Materials like iron, cobalt, nickel, and gadolinium that exhibit strong magnetic effects.

Neodymium

The most common rare-earth magnet made from neodymium, iron, and boron.

Electromagnetism

The use of electric current to create magnets.

Hall Effect

Discovered by Edwin Hall, used to determine the charge carriers in a current-carrying conductor.

Magnetic Force on a Moving Charge

A charge moving into a magnetic field experiences a magnetic force, leading to deflection.

Right Hand Rule

A rule to determine the direction of force on a positive charge in a magnetic field.

Lorentz Force

The combined effect of magnetic and electric forces on a point charge due to electromagnetic fields.
