   How does a coil of wire produce a magnetic field?

   • The magnetic field produced by an electric current in a coil of wire can be visualized as the superposition of the magnetic fields of the current loops which make it up. The fields of the individual current loops add inside the coil to produce a strong and fairly uniform magnetic field. A tightly wound coil is called a solenoid.

   What happens if electric current flows in a coil?

   • If electric current flows in a coil, it experiences a force and moves. Spinning a magnet in a coil of wire generates electricity. Transformers change the size of alternating voltages. create magnetic fields. These magnetic fields cannot be seen.

   How do you draw a magnetic field line in a solenoid?

   • Magnetic field lines of a single circular coil are added up together to make to make the field lines of a solenoid The current in a long, straight vertical wire is in the direction XY, as shown in the diagram. Sketch the pattern of the magnetic flux in the horizontal plane ABCD due to the current-carrying wire. Draw at least four flux lines.

   How does magnetism and electromagnetism occur?

   • Magnetism and electromagnetism occur because of the magnetic fields around magnets and around electric currents. When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass. The strength of the magnetic field is greater: if the current is increased.

   How do you find the magnetic field around a long straight wire?

   • The field around a long straight wire is found to be in circular loops. The right hand rule 2 (RHR-2) emerges from this exploration and is valid for any current segment— point the thumb in the direction of the current, and the fingers curl in the direction of the magnetic field loops created by it.

   5 days ago · An electromagnet utilises this by using a coil of wire called a solenoid. This increases the magnetic flux density by adding more turns of wire into a smaller region of space. One end of the solenoid becomes a north pole and the other becomes the south pole. The magnetic field lines around a solenoid are similar to a bar magnet.
