page 4MakingthemstrongerPicture 8. We deserve to make the electromagnet stronger by enhancing the current, the variety of turns or by placing in a soft steel core.We can make electromagnets stronger in a number of ways. Below are few of them:increase the existing flowinguse an ext turns the copper wireput in a soft iron core.

Let"s look at at each of these.

Bigger currentA bigger current will do a more powerful magnet. However, over there is a limit to how much present can circulation in the wires prior to it gets also hot. Also, a bigger current means that much more energy is wasted (as heat) in the coil and in the connecting wires. So the is often ideal to try to boost the toughness by adding an ext turns fairly than raising the current.

More turnsImagine you have an electromagnet make from a single turn of wire. You then include another turn. It"s prefer putting another electromagnet next to the an initial one. For this reason the strength of the magnet increases. The much more turns, the more powerful the magnet will certainly become.

Picture 9. The magnetic particles in a soft iron nail will certainly line up v the magnetic ar when the present is switched on.Iron coreIron is a magnetic material. There are magnetic particles within the iron. In soft iron, these particles will line up through an outside magnetic field. In this way, the soft iron main point behaves choose a magnet itself. Once the outside field is taken away, the core will return to normal.

Imagine we placed a item of soft steel in the middle of a coil the copper wire. As soon as we move on the current, the coil becomes an electromagnet. Yet also, the soft iron main point becomes a magnet. That will add to the toughness of the electromagnet.

The effect of the soft iron core is much more than copy the existing or the number of turns.
