... The magnetic force is exerted on each moving charge in the wire The total force is the sum of all the magnetic forces on all the individual charges producing the current F = B I ℓ sin θ θ is the angle between B and the direction of I The direction is found by the right hand rule, placing your fi ...

... A changing magnetic field creates a changing electric field. The reverse is also true. A changing electric field creates a changing magnetic field. Electromagnetic waves are produced when something vibrates (an electric charge that moves back and forth). When an electric charge vibrates, the e ...

Magnetism and Electric Currents
... • A solenoid is a long wire wound into many closely spaced loops forming a coil • When current passes through the wound up wire, it produces a strong magnetic field inside of the coil • This is referred to as an electromagnet because the magnetic field only exists when current flows through the wire ...

Preparation PHYS2425 Magnetism lab. Charges cause
... In the lecture we learned that magnetic fields which exist around permanent magnets or electromagnets are caused by currents or moving charges. So a wire that conducts a current will have a magnetic field around it. The magnetic field lines caused by currents are not star-like pattern, but they are ...
