2. You have a horseshoe magnet, but you do not know which end is north or south. Which investigation would give you the answer? aPutting a piece of iron next to the mysterious side. If it is repelled, the mysterious side of your magnet is north.bPutting a piece of iron next to the mysterious side. If it is attracted, the mysterious side of your magnet is north.cPutting the north side of another magnet near one of the poles of another magnet. If the north side attracts the mysterious side, it is north.dPutting the north side of another magnet near one of the poles of another magnet. If the north side repels the mysterious side, it is north.

An iron nail is initially unmagnetised.  Which one of the following things will occur when it is brought closer to the north pole of a permanent bar magnet?Nothing will happen since the iron nail is not a permanent magnetThe iron nail will be repelled by the bar magnetThe iron nail will be permanently magnetisedThe end of the nail which is placed closest to the north pole of the bar magnet will become an induced south pole

A compass needle is a small magnet on a pivot. The needle can swing around freely.Explain why one end of the needle points north.

A magnetic material will become magnetized if:it is placed next to a compassits magnetic domains all face different directionsmost of its magnetic domains face the same directionit is placed next to a piece of iron

Identify whether the following statement is true or false. Some magnets only have a north pole but no south pole.

The force around a magnet can be drawn as a 2D diagram. Determine which two of the following correctly describe the lines that show force around a magnet. The lines can cross overWhere the lines are further apart, the magnetic force is weakerThe lines have arrows to show whether the magnetic force is a push or a pullThe lines have arrows that point away from the north pole, towards the south pole
