Magnets and Electromagnetism

Describe the attraction and repulsion between like and unlike poles of permanent magnets.
Describe the characteristics of a magnetic field, illustrating how its strength and direction change across different spatial points.
Explain how the behavior of a magnetic compass provides fundamental evidence that the Earth's core is magnetic.
Describe the defining differences between permanent and induced magnets.
Describe methods to demonstrate that an electric current can create a magnetic effect.
Describe the geometric pattern and direction of the magnetic field surrounding a conducting wire.
Recall that the strength of a magnetic field around a conductor heavily depends on the magnitude of the current and the distance from the conductor.
Explain how the magnetic effect of a solenoid can be purposefully increased.
