vocabulary:
magnetic force-force attraction or repulsion generated by moving or spinning electric charges magnetic field- electromagnetism-interaction between electricity and magnetism electromagnet-coil that has a soft iron core and acts as magnet when an electric surrent is in its coil electric generator- magnet-any material that attracts iron or any material with iron in it magnetic poles-one of two points that have opposing magnetic qualities domains- solenoid-a coil of wire with an electric current in it electric motor-device that converts electrical energy into mechanical energy electro magnetic induction-process of creating currents in curcuit magnetic field transformers-

pictures
This is a picture of earth's magnetic field,it shows that north and north can't touch,nor can south and south.

This electric gererator is showing the primary and secondary winding of the magnetic course. This is a picture of a solenoid wrapped in a metal coil. This chart shows information about electric fields. E = 1.2 × 102 V/m Volume element at about 2 km height: E = 6.6 × 101 V/m" || 120 N/C 66 N/C ||

Which is the best explanation of magnetic force?

Your answer:

Magnetism is a metal’s gravity.

Magnetism is the attraction between like particles.

Magnetism is the force exerted by an electric current.

Magnetism is none of the above.

The lights of the Aurora Borealis result from

Your answer:

particles from the Sun hitting Earth’s magnetosphere.

static electricity in the troposphere.

lightning storms taking place over the horizon.

rainbows that occur at night.

The Earth's magnetic North Pole changes location over time.

Your answer:

changes deep in the Earth's core

the rotation of the Earth

the Earth revolving around the Sun

Iron filings reveal this in the magnetic field surrounding a bar magnet.

Your answer:

the lines of the magnetic force

the polarity of the magnet

both 1 and 2

neither 1 nor 2
