Unit 13: Electricity Creating Magnetism

For the quiz you will need to understand:

• How baby magnets create a larger magnet which affects where N and S pole
• How N and S pole got their names
• How the magnetic field is defined
• How to draw the magnetic field for a permanent magnet and for the Earth
• How to use the right hand rule to draw the magnetic fields and how to calculate the magnetic fields for a long straight wire, a loop of wire, and a solenoid
• How to to use the OTHER right hand rule (sometimes left) to determine the direction of a force on a moving charge or current carrying wire in a magnetic field as well as determine its magnitude
