Exercise 29.6 Part A A coil 3.85 cm radius, containing 430 turns, is placed in a uniform magnetic field that varies with time according to B=(1.20x102 T/s )t+( 3.00x105 T/s )e*. The coil is connected to a 600-2 resistor, and its plane is perpendicular to the magnetic field. You can ignore the resistance of the coil. Find the magnitude of the induced emf in the coil as a function of time. E = 7.65×10* V +( 7.65×10*$ V/s³ )e² E = 2.40-10°? V +( 6.01×10-5 V/s² )e?

Exercise 29.22 A circular loop of wire with radius 0.0500 m and resistance 0.150 2 is in a region of spatially uniform magnetic field, as shown in the following figure (Figure 1). The magnetic field is directed out of the plane of the figure. The magnetic field has an initial value of 7.94 T and is decreasing at a rate of -0.641 T/s. Figure 1 of 1

Problem 21.19 The magnetic field perpendicular to a single 16.2-cm-diameter circular loop of copper wire decreases uniformly from 0.670 T to zero.

Hey I am doing some physics homework and am stumped on this question.  Any help will be great! Thanks!

A conducting rectangular loop of mass M, resistance R, and dimensions a x b is allowed to fall from rest through a uniform magnetic field which is perpendicular to the plane of the loop. The loop accelerates until it reaches a terminal speed (before the upper end enters the magnetic field). If a = 2.1 m, B = 3.8 T, R = 79 Ω, and M = 0.2 kg, what is the terminal speed? To continue please enter your result in units of m/s. Round your answer to 1 decimal place.

The current I in a long, straight wire is constant and is directed toward the right. Conducting loops A, B, C, and D are moving, in the directions shown, near the wire. a)  Is the direction of the induced current clockwise or counterclockwise, or is the induced current zero for loop D? Briefly explain. b) What is the direction of the net force that the wire exerts on the loop D? (No explanation is needed.) c) Is the direction of the induced current clockwise or counterclockwise, or is the induced current zero for loop C? Briefly explain.

Is this correct? Please explain

Please circle your answers. Thank you

Exercise 29.26 A rectangle measuring 30.0 cm by 40.0 cm is located inside a region of a spatially uniform magnetic field of 1.20 T, with the field perpendicular to the plane of the coil (the figure (Figure 1)). The coil is pulled out at a steady rate of 2.00 cm/s traveling perpendicular to the field lines. The region of the field ends abruptly as shown. Figure 1 of 1 30.0 cm 2.00 cm/s 40.0 cm
