5. This diagram shows two identical coils next to each other. Point A is to the left, and a straight line could be drawn starting from point A through the exact middle of both coils. The left coil is connected to a battery through an open switch as shown. The arrow on the left coil shows the direction in which electric current flows through that coil. At the moment shown, draw the galvanometer needle with its correct position in the...

Two coils shown in the diagram are wound around two iron cores.
The primary coil has 500 turns, self-inductance 7.0 mH and
resistance fo 5.0 ohms. The battery supplies an EMF of 10.0V. The
secondary has 100 turns and resistance 1.0 ohms. The mutual
inductance of the system is 3.0 mH.
a) What is the time constant?
b) How much current is flowing in the primary after one time
constant?

Homework Problem 9.7 The figure to the right shows two con- ducting loops of wire. Loop 1 is connected to a battery through a resistor at time zero and has non-zero inductance. The normal to the surface bounded by the loop lies in the plane of the page. Af- ter the switch is closed, but before the current in Loop 1 reaches a steady state, what effect does Loop 1 have on Loop 2? 2 Select One of the Following:...

please show full solution
Si (a) Athin metallic ring with radius 15cm lies outside of an ideal solenoid (radius Sem) connected to a battery and a switch. The 10cm-long solenoid has 200tums. Explain your answers. (6) At the instant when the switch is suddenly closed, what would be the current direction in the ring? (a) After the switch has been closed for long time, the radius of the ring shrinks to 7cm. What is the current direction in the ring...

1. OBSERVATIONAL EXPERIMENT: HOW TO INDUCE A CURRENT IN A COIL NOT CONNECTED TO A BATTERY The goal of this experiment is to observe 2 sets of videos to find a pattern for the conditions under which there is a current through a coil of wire that is not connected to a battery. Available equipment: Computer with internet connection a) First, make sure you know what a galvanometer is. A galvanometer is a device that registers electric current through it....
