    MaterialStainless Steel
    PhaseSingle Phase
    Model Name/NumberSED1003
    Frequency50 Hz
    Voltage230 V

    Experiments:
    • Exp-1 Verification of Faraday and Lenz's law of induction by measuring the induced voltage as function of time.
    • Exp2 Measurement of the induced voltage impulse as a functionof the velocity of the magnet.
    • Exp-3 Calculation of the magnetic flux induced by the falling magnet as a function of the velocity of the magnet.

    Salient Features :
    • Multipurpose data logger.
    • Easy setup with advanced software features.
    • Microcontroller based digital timer.

    Principle and Working:An induced e.m.f. (or induced current) is produced across a conductor when it is exposed to a change in a magnetic field. The mathematical law that relates the changing magnetic field to the induced current (or the induced voltage) is called Faraday's Law. Lenz’s law describes the magnetic flux through the circuit and gives the direction of the induced e.m.f. This gives rise to induced current which opposes the change in magnetic flux .
    In the present setup, a permanent magnet falls with different velocities through a coil. The change in the magnetic flux generates an induced voltage impulse. The induced voltage impulse is recorded with voltage probe through Data Logger. Depending on the polarity of the permanent magnet the induced voltage impulse is negative or positive.

      ModelSED1002

      Experiments :
      • Exp-1 To measure the magnetic flux density along the x-axis of the circular coils when the distance between them a = R (R = radius of the coils) and when it is greater and less than this.
      • Exp-2 To measure the spatial distribution of the magnetic flux density when the distance between coils a = R, using the rotational symmetry of the set-up.
      • PHYSICS, Class XII, Part - 1, Chapter - 4, Moving Charges & magnetism.

      Special Features :
      • Magnetic filed measure in boh the direction.
      • Distance between coil is adjusted in U channel bench.
      • Modular approach.
      • Electrical safety tested for Power supply & Gaussmeter.

      Principle and Working:
      The magnetic field of the coil arrangement is rotationally symmetrical about the axis of the coils, which is chosen as the x-axis of a system of cylindrical coordinates (x, r, Φ). The origin is at the centre of the system. The magnetic flux density does not depend on the angle Φ, so only the components Bx (x, r) and Br (x, r) are measured.

      In the present setup, a fairly uniform magnetic field is to use a pair of circular coils on a common axis with equal currents flowing in the same logic. For a given coil radius, you can calculate the separation needed to give the most uniform central field.
