• Passing a magnet through the inductor causes current to flow through circuit. 
• EMF magnitude and direction measured via micro-ampere meter and coincident LEDs.
• To the existing inductor we have added an inner inductor with an iron core. This additional inductor allows a greater flexibility in the use of this device, by inducing DC current in the inner inductor. This induction can be controlled by insertion or exertion of the iron core. 
• Two 10mm high brightness LEDs for indication of electrical current direction (Red and Green).
• One high quality neodymium magnet (included).
• One Stainless steel rod (included).
• Two coils for two different experiments.

• 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.
