Review: Magnetism and Electromagnetism

What is the definition of magnets?

Any objects that can be influenced by magnetic field is called....

when a charge is moving in a magnetic field, it will feel

• current

• potential

• force

• speed

which of these statements are true.... (more than one option correct)

• Same poles will repel

• permanent magnet lose its magnetism easily

• the strongest part of magnet is its poles

• if the field lines are separated, the B-field is stronger

Magnet always comes in pairs. There is no magnetic....

What is the name of this device

A device that is use to change the number of voltage transfer from power station to buildings or houses is called....

• Dynamo

• Generator

• Solenoid

• Transformer

Take a look on this picture. If the current is flowing from A to B, choose the correct statement... (there are two correct answers)

• There will be a force that pushes the wire up

• B field above the wire is weaker than below the wire

• B field above the wire is stronger than below the wire

• There will be no force acting on the wire

Draw the magnetic field lines!

When a charge passes through a uniform B-Field in a direction indicated, the charge will feel a magnetic force going into the page

• True

• False
