Short Answer

FIGURE P30.47 shows a 1.0-cm-diameter loop with inside a 2.0-cm-diameter solenoid. The solenoid is 8.0cm long, has 120 turns, and carries the current shown in the graph. A positive current is when seen from the left. Determine the current in the loop at

The current induced in the loop is

See the step by step solution

Step by Step Solution

Step 1:  Lenz's Law

Inside this illustration here, we've shown the approach as from left. This power supplied in the thread will create a magnetic field that resisted the variation due to Lenz's law. In our situation, the stream with in circuit will turn around to achieve this need.

Step 2:Current in the loop

Just to see if can have discover its power in the spiral. The solenoid's magnetic field is consistent, and so its value is calculated

Faraday's law of induction

The magnetic flux is the current

Step 3: Ohm's Law

The loop of current using Ohm's law

The graph depicts the change of piezo power - the charging current. by
