Electricity and Magnetism SPS10

This is a picture of a simple electromagnet. How can the electromagnet be made stronger?

• Add more coils of wire to the nail.

• Use a smaller battery (less potential difference).

• Reverse the poles of the magnet.

• Flip the battery around so the current runs in the opposite direction.

Use your equation sheet.

What size resistor would produce a 3 Amp current flow with a 12 Volt battery

• 1 Ohm

• 3 Ohms

• 4 Ohms

• 12 Ohms

Use your equation sheet.

If the battery produced 12 Volts what would be the current flow for a 6 Ohm resistor?

• 2 Amps

• 0.5 Amps

• 72 Amps

• 18 Amps

Potential Difference and Current are ____ related.

• directly

• inversely

• not

Resistance and Current are ____ related.

• directly

• inversely

• not

Choose the options that will increase the current flow.

• Increase the resistance

• decrease the resistance

• increase the voltage

• decrease the voltage

This type of circuit has one path and the current everywhere is the same.

• alternating

• series

• parallel

• direct

Magnetic fields flow

• only inside the magnet.

• in circles around the magnet.

• from the north pole to the south pole.

• in random directions from all parts of the magnet.
