The easiest way to create a powerful magnetic field is by creating a powerful electromagnet. Electromagnets are used for everything from powering tiny electronic switches (called relays) to lifting huge pieces of scrap metal. The density of the winding, the amount of current flowing through the m...

The electromagnetic brake comprises a frame part, an armature part movably mounted on the frame part and having a magnetic core, one or more spring elements for activating the brake by moving the said armature part forwards, an electromagnet fitted to the frame part and arranged to release the...
You can also go all out and create an electromagnet out of your metal that will create a magnet field that will either be attracted by or repelled by other magnets. To make an electromagnet out of your metal, wrap and coil wire around it completely and attach both ends of the wire to...
Rubbing the magnet against the needle in one direction caused the iron atoms in the object to line up and create a weak magnetic field, which made the needle behave like a magnet. You had to rub in one direction to get the atoms to all line up in the same manner. If you had rubbed...

The goal of the ignition coil is to create an electromagnet by running the 12 volts supplied by the battery through the primary winding. When the vehicle’s ignition system triggering switch turns off the power to the ignition coil, the magnetic field collapses. As it does, the secondary wind...

Here, an electromagnet is used to pick up some of the approximately 3,500 confiscated guns to be melted down. David McNew/Getty Images What do a wrecking yard, a rock concert and your front door have in common? They each use electromagnets, devices that create a magnetic field through ...
