Experiments of MAGNETISM

DEFLECTION MAGNETOMETER

P-715 INSIF
* A compass box : is mounted at the centre of a wooden board( 1 meter long)
* A metric scale: extending outward from each side of the compass box for observing the position of the magnet tested.
* Fitted an Aluminum Cup : at the centre for holding compass box.


DIP CIRCLE

P-718 INSIF
* Case: Aluminium Ally 120mm dia with removable windows both sides.
* Base: tripod base with 3 leveling screws.
* Horizontal scale: 125mm dia graduated clock 360° x 1°
* Inclined scale: Brass 105mm dia graduated 90° - 0 -90° x 1°
* Magnetized needle: is 90 mm long with hard ended steel pivots working in a agate cup bearing.

EARTH INDUCTOR

P-720A INSIF
* Al. metal ring : (6” dia) on which a coil is wound (of either 500 or 1000 or 2000 turns ) of 36 SWG.
* A stop limiting rotation : to 180° of ring is provided with the help of a spring.
* The cradle supporting : the coil non-magnetic alloy 200 x 210 x 115 mm high may be placed either on its base or side so that the axis of rotation of the coil is either horizontal or vertical. * Provided with the terminals.

Electro Magnet with Txr

Main operated P-721 INSIF
Exp : to find the frequency of AC MAINS by sonometer.
It consists of a coil : wound of copper wire of 22/24 SWG on metal rod with non conductive handle with two brass terminals to be connected to transformer 6VDC fitted on Bakelite base, * * * input 220VAC.


ELECTRICAL VIBRATOR

P-724 INSIF
* A thin steel rod (called vibrator) is clamped at one end and passes through a small solenoid.
* The rod is slightly flattened at the free end and a hole is drilled in it so that string can be tied to the rod through this hole.
* The solenoid : is connected to AC mains through a suitableclamp on the base board and a steel rod passes between them. The thin rod is magnetized longitudinally. The solenoid and a horse * shoe shaped magnet causes it to vibrate with the frequency of AC supply.
* The length of the vibrator is adjusted until its natural frequency corresponds with that of supply.
* The whole unit is mounted on a polished wooden base.
* Complete with pulley, pan and cord.


MAGNETOMETER VIBRATION INSIF P-784


A polished box:Is fitted with leveling screws and having back and front sliding doors.
* A Glass Tube: front sliding doors fitted with simple torsion head to support, by means of a silk fiber, a wire holder holding a magnet.
* Complete with one magnet & a brass bar/strip.
B) Brass

Solenoid Inductor

P-720B INSIF
Usage: Instrument for calibrating a ballistic galvanometer.
* Primary Coil: has 1000 turns & is 100 cm long fitted on a wooden board.
* Secondary: is in section with separate terminals for each section Every section of the secondary has its own number of turns marked on the wooden board. Secondary coil has three tapings of 100.250. 500 turns.


FARADAY EFFECT

cat no P-876B



three copper coils fitted on a bakelite plate fixed on a wooden box

this works on principal, some current is produced when magnet passes through copper coils

the coils are connected with three terminals, which can be connected with ammeter or galvanometer separately

supplied with special meter to read current

supplied with one magnetic bar
