Current in Solenoid

• Purpose: Illustrate principles of electro-magnetic induction.
• Send current through solenoid and measure direction of B-field using B-field indicator (magnaprobe). Place coil of wire in front of solenoid and quickly adjust current, galvanometer will indicate induced emf consistent with Lenz's law.

Location

• Solenoid and wire coil located in L01, section B2.
• Power supply- L35, section F1;
• magnaprobe- L35, section E4, top shelf
• galvanometers- L35, section F3
