Magnets
- The magnetic field is a region where other magnets or magnetic materials experience a non-contact force
- The force between two, unlike poles, is attractive
- When a compass is far away from a magnet, it points north
- The force between a magnet and a magnetic material is always attractive
Basic Electromagnetism
- The magnetic field goes around a current, carrying wire in circles
- Adding more turns to a solenoid increases the strength of its magnetic field because of the field lines around each loop of wire line…
