Magnets revision

Use these slides to help you answer the questions

These element metals are magnetic:

- iron

- cobalt

- nickel

Steel is mostly iron, so steel is magnetic too

Magnets interact through their magnetic fields

They have two poles, north, and south.

Their fields always move north to south.

Opposite poles attract

Like poles repel

Can represent the attraction and repulsion forces using force arrows

Magnets produce their own magnetic fields

We can draw these

Magnetic fields are ALWAYS from north to south poles.

Multiple Choice

Are the magnetic field lines in the picture correct?

• Yes, because they point from north to south.
• No, because they point from north to south (they're supposed to go the other way).
• Yes, because the North pole is on the left in all pictures.
• No, because the North pole is on the left in all pictures (it's supposed to be on the right).
