A 9.6 cm-diameter circular loop of wire is in a 1.10 T magnetic field. The loop was removed from the field in 0.15 s. What is the average induced emf?

A 105-turn square wire coil of area 0.040 m2 rotates about a vertical axis at 1,800 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. 20.0 cm 20.0 cm V

An emf is induced by rotating a 1107 turn, 20.0 cm diameter coil in the Earth's 3.53 x 10-5T magnetic field. What average emf is induced, given the plane of the coil is originally perpendicular to the Earth's field and is rotated to be parallel to the field in 10.0 ms?

What is the peak emf generated by rotating a 1000-turn, 20.0 cm diameter coil in the Earth’s 5.00 X 10-5 T magnetic field, given the plane of the coil is originally perpendicular to the Earth’s field and is rotated to be parallel to the field in 10.0 ms?

003 A circular coil of wire 7.8 cm in diameter has a resistance of 1.61 2. It is located in a magnetic field of 0.304 T directed at right angles to the plane of the coil. The coil is removed from the field in 0.169 s. What is the induced emf in the coil? As- sume the magnetic flux is reduced linearly. Answer in units of V. How much electric energy is lost in the process? Answer in units of J.

A 500-turn circular loop 15.0 cm in diameter is initially aligned so that its axis is parallel to the Earth's magnetic field. In 2.77 ms the coil is flipped so that its axis is perpendicular to the Earth's field. If a voltage of 0.166 V is induced in the coil, what is the value of the Earth's magnetic field?

Gabriel and Akito now decide to work a problem. A loop of wire in the shape of a rectangle rotates with a frequency of 310 rotation per minute in an applied magnetic field of magnitude 6 T. Assume the magnetic field is uniform. The area of the loop is A = 2 cm² and the total resistance in the circuit is 7. Find the maximum induced emf. E. = 6.2004e-3 X V max Find the maximum current through the bulb. Imax 8.857 XA -

A conducting wire shaped in a “U shape” is connected to a  5 ohm light bulb.The 0.8 T external magnetic field is directed into the page as shown.  A conducting bar of length 1.2 m is sliding on the conducting  wire at 2 m/s to the right. What is the induced emf? Hint:  the induced emf is the negative of the change in magnetic flux. The magnetic flux changes because the area of the U shaped wire placed in the magnetic field changes when the conducting wire slides to the right.  Induced emf <=>   emf = -N ∆Φ/∆t∆Φ =∆(BA)= B ∆A =B  ( Af-Ai) Group of answer choices A) 1.92 V B) 0.8 V C) 2.4 V D) 6.8 V   Please show how you solved the question and provide explanations. I am struggling in this section of physics, so I greatly appreciate your guidance.
