Coils usually refer to toroidal wires, and the most common coil applications are: motors, inductors, transformers, and toroidal antennas.
Coil turns are the number of turns of the wire around the object.

The magnetic induction intensity of each point on the axis of the current-carrying circular coil and Helmholtz coil is measured
1. When the current I=300 mA is measured, the magnetic induction intensity B1 at each point on the axis of coil 1. A set of data is required to be measured at intervals of 1.00cm.
2. The measured magnetic induction intensity on the axis of the circular coil is compared with the theoretical calculation results.
3. The distance between coil 1 and coil 2 is equal to the radius of the coil, that is, d=R. Take the current I=300 mA, and measure the magnetic induction B1 and B2 of each point on the axis when coil 1 and coil 2 are powered on separately (current direction is the same). Then, the magnetic induction B1+2 of each point on the axis of the Helmholtz coil is measured by passing an equal current I=300 mA in the two coils.
