How can we make a magnet

Most magnets are formed by moving electrons. Each moving electron creates a small magnetic field. If lots of  electrons are moving along the same path, they create a bigger magnetic field. Because of this you can make a magnet by using electric current. If you wrap a coil of wire around a piece of iron (like a big nail) and then  put electricity through it using a battery, you will create a magnetic field. This is what we call an "electromagnet."
