What is the magnetic effect of electric current?

Ans: When electricity flows through a wire, the wire acts like a magnet. This is called the magnetic effect of electric current. But if there’s no electricity flowing through the wire, it won’t act like a magnet anymore. We call these special wire coils “electromagnets.”

The magnetic effect of electric current is super important in our world. It’s what makes things like electric motors work. When there’s electricity in a wire, it creates a magnetic field around it. You can imagine this field like invisible lines called magnetic field lines.

Imagine you have a straight wire with electricity running through it. The magnetic field lines form circles around the wire, like when you drop a pebble into a pond, and you see ripples in the water spreading out from the center.
