Magnetic field is very amazing and abstract. At now, a lot of people ask that: what does a magnetic field look like? This is a good question. I have some idea of magnetic field would like to share with you.

First, do you know what is the magnetic field? That means around the magnet, there is a substance that can deflect the needle, this kind of material is called a magnetic field. We can't see or touch that, but can take the needle into the magnet, oversee the deflection of the needle can sense the magnetic field exists. Amazing isn't it ?

Second, the traditional way to visualizing magnetic fields is to place a magnet bear a surface covered with iron filings.

There is another way to see the the magnetic field, it can use green magnetic field viewing paper or using Finite Element Analysis software.
