What is the direction of the induced current if the field B suddenly decreases as the loop is moved through the region? Ø clockwise counter clockwise no induced current X

The current in a long solenoid of radius 6 cm and 22 turns/cm is varied with time at a rate of 3 A/s. A circular loop of wire of radius 8 cm and resistance 7 0 surrounds the solenoid. Find the electrical current induced in the loop (in HA). HA

The figure shows a uniform magnetic field that is normal to the plane of the conducting loop of resistance R. Note: the area of the non- circular portion of the circuit is negligible compared to that of the loop. B 04 Which entry in the table below correctly pairs the change in the system with the direction of the induced current through R? change in the system direction of current through R decrease the area of the loop rotate loop into the paper decrease the magnitude of B increase the area of the loop pull loop to the right from top toward bottom no induced current from bottom toward top from bottom toward top from top toward bottom

A loop is fixed in position in the location of a magnetic field directed out of the page.  The magnetic field gets weaker over time. Determine the direction of the induced current in the wire.

You drop a magnet north pole side down from a height (h) into a loop of wire, inducing a current. Draw a graph showing how the induced current in the loop depends on time as the magnet falls through the loop. Does the magnitude of the induced current depend on h?

In each of two coils the rate of change of the magnetic flux in a single loop is the same. The emf induced in coil 1, which has 245 loops, is 2.51 V. The emf induced in coil 2 is 4.90 V. How many loops does coil 2 have? Number i 480 Units No units

A circular loop with a radius of 0.21 m is rotated by 90.0° over 0.210 s in a uniform magnetic field with  B = 1.40 T.  The plane of the loop is initially perpendicular to the field and is parallel to the field after the rotation.
