# Models for Magnetism

This sampler of models for Magnetism is organized by topics. Navigate to the simulations by opening the folder and then double-clicking on the green triangle to launch.

#### Magnetism:

- Magnetic Bar Field (B Field)
- Magnetic Multipole (B Field)
- Charge in a B Field (Lorentz force)
- ExB Field Trajectory: Incomplete Model (Lorentz force)

#### Currents and Fields

- Magnetic Field from Loops (Current and Field Vectors)
- Current Wire Pendulum (F = ILxB)
- Rail Gun (F=ILxB)
- Helmholtz Coils (Current, Field Vectors and Lorentz force)

#### Faraday

- Falling Loop (Faraday)

- Moving Magnet (Lenz's law)
- Falling Magnet Eddy Current (Faraday, Induced emf)
- Falling Magnet Superconductor (Faraday, Induction)
- Faraday Disk Dynamo (Faraday, Induced emf)
- Faraday Loop: Incomplete Model (Faraday, Induced current)
- Generator (Faraday, application)

#### Solutions

- ExB Trajectory: Solution
- Faraday Loop: Solution
