Demonstrates: Direction of a magnetic field. Description: Direction of current causes different deflections. |
 |
5H 10.30 - Magnetic Needle with Current Loop:
Demonstrates: Magnetism. Description: Dip meter. |
 |
5H 15.20 - Induced Electrical Field:
Demonstrates: Current caused by a magnetic field. Description: Back and forth motion through magnetic field causes small bulb to light up. |
 |
5H 15.30 - Solenoids:
Demonstrates: Amphere's Law. Description: Law can be used to find the magnetic field inside loops of a current carrying wire. |
 |
5H 15.40 - Magnetic Field Around Current Carrying Wires:
Demonstrates: Magnetic field lines. Description: Sprinkle iron filings on charged plate to get field lines. |
 |
5H 20.40 - Suspended Bar Magnet:
Demonstrates: Magnetism. Description: Suspended magnet can be deflected with another magnet. |
 |
5H 30.10 - Cathode Ray Tube:
Demonstrates: Kinetic energy of particles. Description: A windmill on a track in a glass tube spins when hit by electrons. |
 |
5H 30.20 - E/M Tube:
Demonstrates: Effect of electric and magnetic fields on a beam on a stream of electrons. Description: Produces an arc of electrons that is clearly visible. |
 |
5H 30.30 - Crooke's Discharge Tube (Heating Effect):
Demonstrates: Heating effect. Description: Discharge tube contains a thin metal target that becomes red hot after being bombarded by electrons. |
 |
5H 30.40 - Crooke's Discharge Tube (Magnetic Effect):
Demonstrates: Magnetic effect. Description: Discharge tube has a florescent coated screen with a slit near the negative electrode. In a magnetic field a luminous line is bent upwards or downwards depending on the direction of the field lines. |
 |
5H 40.10 - Force on Parallel Wires:
Demonstrates: Direction of field lines. Description: Two wires are given a current. If the current is in the same direction the wires repel each other. Opposite directions, the wires are attracted to each other. |
 |
5H 40.30 - Jumping Wire in Magnetic Field:
Demonstrates: Direction of electrical current. Description: Place wire between poles of permanent magnet. When current is applied wire will either jump up or down depending on the direction of the current. |
 |
5H 50.10 - Einstein de Haas:
Demonstrates: Torque. Description: A current through the apparatus causes a torque that deflects the laser reflection. |
 |
5H 50.20 - Guillermo's Magnetic Field:
Demonstrates: Precession. Description: A spinning billiard ball on a cushion of air precesses due to a magnetic field. |
