Magnetic Fields and Forces

Fields and Currents

• Magnetic Fields Around Permanent Magnets

• Magnetic Field Around a Current Carrying Wire

Compasses are used to visually demonstrate the magnetic field around a current carrying wire.

• Magnetic Field Around Various Currents

Compasses are used to visually demonstrate the magnetic field around a pair of coils and a toroid.

Force on Moving Charges

• Magnetic Force on an Electron Beam (Using e/m Apparatus)

An electron beam is deflected into a circle between a pair of Helmholtz coils.

• Lorentz Force (Crookes Tube)

An electron beam is deflected using a magnet.

• Jumping Wire

Force on Current in Wires

• Force Between Parallel Wires

• Ampere Balance

• Torque on a Current Loop
