Electric charges and magnetic fields are closely connected because of something called electromagnetism.

How Electric Charges Create Magnetic Fields: When an electric charge moves, it makes a magnetic field. Think about when electricity flows through a wire. This movement creates a circular magnetic field all around the wire. To picture this, you can use the right-hand rule: if you point your thumb in the direction the current is going, the way your fingers curl shows which way the magnetic field is spinning.

How Magnetic Fields Affect Electric Charges: On the flip side, magnetic fields can also have an effect on electric charges. This idea comes from Faraday's law of electromagnetic induction. It says that when a magnetic field changes inside a loop of wire, it can create an electric current. For example, if you move a magnet through a coil, it produces a current. This shows how magnets can influence electricity.
