What are two different ways of making permanent magnets?

Answer 1

By using a permanent magnet to stroke a piece of magnetic metal to make another magnet, or by making an electro-magnet. For more information please click on the Related Questions shown below.

Answer 2

One way is with the use of another magnet, where you rub one pole of another magnet along the iron rod for a hundred times. You must always stroke in one direction only and always lift off the magnet from the iron rod at the end of each stroke.

Another way is by using electricity from a battery: coil very thin insulated wires around an iron rod and connect the battery to the circuit. This will magnetize the iron rod temporarily until there is no more electricity in the circuit.

Giving something a magnetic charge is very easy. However, it won't work as well as a magnet that you buy.

Steps to follow:

1. Get a metal object. A paper clip works well for this.

2. Get a magnet.

3. Move the metal object quickly across the magnet in the same direction. You need to repeat this 50 to 100 times.

4.Try to pick up a paper clip with the metal object you rubbed across the magnet. It probably will just barely lift it up because it is not strong at all.

You can also make an electromagnet:

1. Get a small guage wire.

2. Bare the wire on both ends about 1 inch or so.

3. Working center out on the screw driver and wire, coil the wire around the screwdriver about 20-30 times. (10-15 either way)

4. Connect one end of the wire to the + end of a 9 volt battery and the other to the - end. See how many paper clips you can pick up.

Answer 3

Detergent maintains its cleaning power better than soap over a long period of time. For household managers who are looking to economize, this means they can purchase the larger size of detergent at a lower unit cost and not have to worry that its cleaning ability will subside while in storage.

Answer 4

1. Using ferromagnetic materials like iron, nickel, or cobalt, to create a permanent magnetic field through a process of magnetization.
2. Heating a ferromagnetic material above its Curie temperature and then cooling it in the presence of a strong magnetic field to align the magnetic domains in the material and create a permanent magnet.

Answer 5

i think its rubbing on the ferromagnetic material by using a permanent magnet. so it can become magnetized.

Answer 6

you would need metal,fire/heat,and ice/cool air

Answer 7

Casting and Injection Molding

Answer 8

unmagnetized material pressentation
