Electromagnet, Electromagnetic Coil and Permeability

The introduction of this type of material into a magnetic circuit has the effect of concentrating the magnetic flux making it more concentrated and dense and amplifies the magnetic field created by the current in the coil. We can prove this by wrapping a coil of wire around a large soft-iron nail and connecting it to a battery as shown.

Ferromagnetism - HyperPhysics Concepts

Ferromagnetism Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example. Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets.

4. You will need to use EMF magnetic shielding to shield against the magnetic, not just the electronic, part of the EMF/EMI/RFI. EMF magnetic waves function differently than EMF electronic waves, since they bounce back or beam back to their source. According to lessemf.com, "magnetic field lines must travel from the North pole of the source and return to the South pole.

physics - Britannica.com

Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements. It also occurs in gadolinium and a few other rare-earth elements. In contrast to other substances, ferromagnetic materials are magnetized easily, and in strong magnetic fields the magnetization approaches a definite limit called saturation.

3 Ways to Magnetize Metal - wikiHow

 · As long as a metal has some iron in it, you can magnetize it using another magnetic metal or an electromagnet. While you need a strong magnet to make another metal magnetic, the magnetism produce will probably not be very strong; it will be sufficient to pick up a paperclip or a screw. The strength of the magnet depends upon the iron content.

How Magnets Work - Real World Physics Problems

A piece of iron can be picked up with a magnet, even if it is originally non-magnetic. When the iron is placed near a magnet its magnetic domains (consisting of billions of magnetically aligned atoms) become aligned causing the material itself to become magnetic (with a north and south pole). It can then be picked up by the magnet.
