What is an induced magnet?

How can you plot a magnetic field?

• Using Google Maps

• Using a plotting compass and bar magnet

• Using a compass and a magnet

• Magnetic fields are unplottable

Where is the magnetic field strongest on a bar magnet?

• Furthest away from the poles

• In the middle

• Nearest to each pole

• Overall, bar magnets are weak

The north pole of a magnet is attracted to

• Other north poles

• South poles

• East poles

• West poles

The south pole of a magnet is attracted to

• East poles

• West poles

The arrow in a compass is...

• Pointy

If you point your right thumb in the direct of the current, the magnetic field goes...

• POP (like the weasel)

• Around the wire parallel

• in the direction your fingers are pointing

• Nowhere

The higher the current,

• the weaker the magnetic field

• the stronger the magnetic field

The magnetic field is strongest

• The closer it is to the wire

• The further it is from the wire

• On the left side

• Towards the positive terminal
