Try and picture a magnet in your head? Is your mental image clear now and does the magnet you’re picturing resemble a horseshoe? It does, doesn’t it?
I know it does because when we think of magnets we tend to think of the traditional horseshoe magnet. This shape is iconic when it comes to magnets and it is for a reason. The image has been planted in our brains from many experiments in science lessons at school when we were kids.
Can you remember all the facts about horseshoe magnets from those lessons back then? No? Don’t you worry, ‘caus we’re gonna tell you all about the iconic horseshoe magnet in this blog post. No need to thank us. You’re so very welcome!
Why is it called a horseshoe magnet?
The reason a horseshoe magnet is shaped like a horseshoe is to increase the magnetic flux at the lifting end. In the lifting end, it has high peak fields because there are two opposite poles there. In contrast, a typical bar magnet only has half the peak “lifting power” since there is only one pole where lifting is done.
Why is a horseshoe magnet stronger?
A horseshoe magnet is a bar magnet in a U-shape. The U shape makes the magnet stronger by pointing the poles in the same direction and therefore has twice the peak “lifting power” compared with a regular bar magnet.
How does a horseshoe magnet work?
A horseshoe magnets works by attracting ferromagnetic materials from different surfaces. A horseshoe magnet has two magnetic poles close together, which means there is a straighter path for the flux lines and as a result, the magnetic field gets stronger between the two magnetic poles.
Where is the field of a horseshoe magnet strongest?
Because a horseshoe magnet is the same as a bar magnet it is, like a bar magnet, also strongest at either pole of the magnet. This mean it is equally strong at the north pole when compared with the south pole whilst the force is weaker in the middle of the magnet.
What is the correct way of storing a horseshoe magnet?
It is very important to store your magnets correctly. You can’t just put down on the table or in a drawer because there is a good chance they attract something and potentially ruin that thing. The correct way of storing horseshoe magnets is end-to-end with opposite poles touching.
Do the poles of a horseshoe magnet attract each other?
Yes, they actually do. The poles of a horseshoe magnet attract each other obviously because they have opposite polarity. When a magnet is bent in the shape of a U or a horseshoe magnet, the poles, of course, get closer to each other and the force between them increases.
Where is a horseshoe magnet used?
Horseshoe magnets are mostly used in school classrooms for teaching and demonstration the course of magnetic field lines. They are also used in dynamos for bicycles and in the area of model construction.
