How to Make a Magnet?
We make magnets by exposing ferromagnetic metals like iron and nickel to magnetic fields. Moreover, when we heat these metals to a certain temperature, they get permanently magnetized. Besides, it’s also possible to temporarily magnetize them by using a variety of methods that you can try safely at home. Learn how to make a magnet, like a paperclip, an electromagnet, and a magnet you can use as a compass.
Paper Clip Magnet
In how to make a magnet, the easiest way is to make paper clip magnet.
Collect goods- A simple temporary magnet, such as a paper clip and a refrigerator magnet, can be made with a small piece of metal. Collect these objects as well as a narrower piece of metal, such as an earring or a small nail, which you can use to check the magnetized paperclip’s magnetic characteristics.
Furthermore, experiment with various dimensions of paperclips and uncoated versus covered paperclips. In a variety of dimensions and metals, collect larger items to see which ones will stick to the paper clips.
Rub the paperclip magnet against it- Instead of moving it back and forth in the same path. Use the same fast movement to light a game. Continue scratching the paper clip 50 times faster than you can with the magnet.
Touch the clip against the narrower metal piece- Does the tiny metal piece stick to the clip? If so, you magnetized it successfully. If the metal does not stick to the paper clip, rub it 50 times more and try again.
To determine how powerful the magnet is, try to pick up other paper clips and bigger items. Consider recording the length of time after a certain number of rubs the paper clip stays magnetized.
Collect goods- Electromagnets are developed to produce a magnetic field by passing an electrical current through a piece of metal. Using these materials accessible in hardware stores, this can be achieved on a tiny scale:
- a big iron nail
- 3 feet thick covered copper wire
- A D-cell battery
- Small electronic items, such as paper clips or buttons
- Wire strippers Masking tape
Strip the wire ends- Use the wire strippers to extract from either end of the copper wire a few centimeters of insulation. The uninsulated ends around the ends of the battery will be wrapped.
Wrapped nail- Starting at the bottom of the wire about 8 inches, knot the nail closely. Every strap should touch the last, but do not overlap it. Continue winding until you cover the nail from top to tip.
Also, make sure that you squeeze it down the nail in the same manner. The electricity must flow in the same direction to generate a magnetic field.
Connect Your Battery- Wrap one end of the exposed wire around the battery’s favorable edge and the other end around the battery’s adverse side. Use a small piece of masking tape to secure the wire on both sides.
In addition, don’t care about the bottom of the wire at which end of the battery you are attaching. Either manner, the nail will become magnetized; the only distinction is that it will alter its polarity. Moreover, the north pole is one part of the magnet, and the south pole is one side.
The cables will reverse the poles as well. The cables will develop warm once the battery connects, as electricity starts to pass through them, so be cautious not to fire yourself.
