Asadbek investigates a steel needle floating on water.
In his first experiment Asadbek:
passes a steel needle over a strong magnet
floats the steel needle on the surface of the water.
She repeats the experiment five times. Each time she floats the steel needle in different directions on the surface of the water.
The needle turns to point in the same direction every time. Explain why. You need to give two ideas
The needle is magnetized or magnetic
So it lines up with Earth's magnetic field
