If 53.5 cm of copper wire (diameter = 0.828 mm, resistivity = 1.69 × 10-80-m) is formed into a circular loop and placed perpendicular to a uniform magnetic field that is increasing at the constant rate of 12.5 m/s, at what rate is thermal energy generated in the loop? Number Units

Suppose you have a long, skinny conductor that is oriented with its long axis parallel to a uniform magnetic field. Suppose also that the conductor is moving along its long axis in a straight line at constant velocity v. Despite the motion of the conductor, no motional emf is induced. Why? The magnetic field is too uniform The velocity has no component normal to the magnetic field The velocity is too low The conductor is so long and so thin that its electrical resistance is too high

005 A uniform electric field of magnitude 5.06 x 10 V/m throughout a cylindrical volume re- sults in a total energy of 2.95 µJ. What magnetic field over this same region stores the same total energy? Answer in units of T.

suppose a conducting rod with length of 25cm is pulled along the a rotated U-shaped conductor (assume that resistance is negligible), the magentic field has a constant value of 37.2 mT and the constant velocity at which the rod is pulled is 5.5m/s. identify the minimum rate of energy input to the system to keep the rod moving at constant velocity if it has a resistance of 7ohms

A 100-turn square wire coil of area 0.040 m² rotates about a vertical axis at 1,470 rev/min, as indicated in the figure below. The horizontal component of Earth's magnetic field at the location of the loop is 2.0 x 10-5 T. Calculate the maximum emf (in V) induced in the coil by Earth's field. V 20.0 cm 20.0 cm

A coil with 35 turns sits in a magnetic field. The cross-sectional area of the coil is 5.1 cm2. If the magnetic field uniformly reduces from 1.0×101 T to 1.5 T in 6.5 seconds, what is the magnitude of the induced emf in that coil?

The magnetic field at a distance r=50 cm away from the wire is 6.8 x 10(-7) T. Compute the wire's current.

QUESTION 7 Refer to the figure in the previous question. What is the emf induced when a 5.48-cm conducting rod attached to a U-shaped conductor moves at 1.56 m/s perpendicular to a magnetic field of strength 14.9 T? Please write the numeric answer in terms of V (volts). Normal format with 3 SF.

Magnetic flux is measured in webers which can be expressed in units of V*s (V = volts). The magnetic flux was 14.993 V*s. What is the magnetic flux in kV*µs?
