2. An electron has a speed of 1.4 x 106 m/s. It travels through a 3.8 T magnetic field that is perpendicular to its velocity. An electric field is perpendicular to the B field and the velocity of the electron. The electron's velocity is constant. Find the magnitude of the electric field.

Question 1: #65       The 10-cm-wide, zero-resistance wire shown in Figure below, is pushed toward the 2.0 Ω resistor at a steady speed of 0.50 m/s.  The magnetic field strength is 0.50 T. a. What is the magnitude of the pushing force? b. How much power does the pushing force supply to the wire? c. What are the direction and magnitude of the induced current? d. How much power is dissipated in the resistor?

3. Induced Forces: Two conducting coils are arranged parallel to each other. The first coil is connected to a power supply so that the current is in at the top and out at the bottom. The voltage on the power supply is being decreased. a. What is the direction (left/right/zero) of the magnetic field (due to the first coil) as it goes through the 2nd coil? b. Is the magnetic flux increasing or decreasing? c. What is the direction of the induced magnetic field through the 2nd coil required to resist the change in magnetic flux? THK ε d. What is the direction (in at top/out at bottom or out at top/in at bottom) of the induced current in the 2nd coil required to produce the induced field needed? e. What is true of the magnetic force between the two coils? • The coils will attract each other. • The coils will repel each other. • There is no magnetic force between the coils. f. What is the direction of the induced current in the 2nd coil if the voltage of the power supply for the first coil…

The induced magnetic field at radial distance 5.8 mm from the central axis of a circular parallel-plate capacitor is 1.8 × 10-8 T. The plates have radius 4.0 mm. At what rate is the magnitude of the electric field between the plates changing? Number i Units

2. The figure below shows a metal plate with a width of w = 2 cm and a thickness of t = 0.1 cm. An electric current I = 20A is applied to it and placed in a magnetic field B in the direction shown in the figure. When the applied magnetic field is 2 tesla, the resulting Hall voltage of 4.28 V. Based on the above, determine the electron drift velocity (Vd)!

18. Two very long conductors (both oriented in the same plane) are shown in the sketch below. The same magnitude of conventional current in each is represented by the red arrows.
