    Moving charged particles creates magnetic fields. This was first observed in the early 19thcentury. During an experiment, it was observed that when an electrical current flowed through a wire, a nearby compass would change directions. When the current was turned off, the compass would go back to its original north/south alignment with the Earth’s m...

    Electromagnets are magnets whose magnetic field is produced by an electric current. It displays a magnetic attraction to other metallic objects when an electric current is passed through them. We can also control and switch on and off the power of its magnetic attraction.

    Magnet wire or winding wire is an insulated conductor used for interchanging electrical energy with magnetic energy. Usually, it is coated with copper or aluminum with a thin layer of insulation. It has three types: enameled wire, conductor wire, and the combination of the two. They are commonly used for inductors, motors, potentiometers, electroma...

    Faraday’s Law of Induction states that a changing magnetic field will induce an electromotive force (emf) in a loop wire. The electromotive force causes electrons to move and form a current. Changing the area of the loop of wire and changing the angle between the loop and the magnetic field can both induce a current. This is because of the property...

  4. The magnetic field for a coil of wire is shown below. The magnetic fields from each of the turns in the coil add together, so the total magnetic field is much stronger. This produces a field which...

  5. 5 days ago · Magnetic fields in wires, coils & solenoids. Magnetic fields are formed wherever a current flow, such as in: long straight wires. long solenoids. flat circular coils. Magnetic field around a current-carrying wire. Magnetic field lines in a current-carrying wire are circular rings, centred on the wire.

  7. Magnetic Field Produced by a Current-Carrying Solenoid. A solenoid is a long coil of wire (with many turns or loops, as opposed to a flat loop). Because of its shape, the field inside a solenoid can be very uniform, and also very strong.
