The jobs that I can think of that use magnets are:
- Scrap metal firms - This was the first job that came to mind when thinking of jobs that use magnets, as the magnet used in a scrap metal firm is so big!
The magnet on machines used in this industry sits on the end of a crane, and enables workers to be able to sort different metals from each other, as only some types of metal will stick to the magnet.
- Train drivers- Magnets are used by train drivers as they are used in a trains automatic warning systems, the magnets in the train and in the track allow the train to be warned when approaching a signal.
- Clothes shop worker- This may sound like a strange one, but magnets are used to take the alarms off clothes before you are allowed to take them out of the store. A magnet fixed into the shops counter is stronger than the one in the alarm, and therefore pulls the alarm off the garment when put near the stronger magnet.
- Doctors - Doctors will use magnets in some of the equipment they use, such as when giving an MRI scan. There is also research into using magnets to give pain relief.
- Navigators - People that work for example, on a ship, will use magnets to help them navigate by using a compass. A compass works by the needle on the instrument matching with the Earth's magnetic field, so will always point North.
