Current scale

- A wire winds an optional number of windings
between two static magnets at the base of the apparatus.
The base can be rotated at marked angles. It is
placed upon a sensitive scale (not included).
- This device allows measurements of the magnitude
of the force a magnetic field imposes upon a
current carrying wire as dependent upon:
- The length of the conducting wire.
- The magnitude of the current
- And the angle between the direction of the
magnetic field lines and the direction of the current.
