Chapter 28, Problem 042 The bent wire shown in the figure lies in a uniform magnetic field. Each straight section is 2.78 m long and makes an angle of θ=42.1° with the x axis, and the wire carries a current of 1.21 A. What is the net magnetic force on the wire in unit-vector notation if the magnetic field is given by (a)3.91 kT? (b)3.75 İ T?
Problem 4 Magnetic field region Fig. 2 A long wire carrying 4.50 A of current makes two 90° bends, as shown in Fig.2. The bent part of the wire passes through a uniform 0.240-T magnetic field directed as shown in the figure and confined to a limited region of space. Find the magnitude and direction of the force that the magnetic field exerts on the wire. . ||30.0 cm 60.0 cm 4.5 Y_ - 60.0 cm
Problem 5: A 5 cm long wire is in a uniform magnetic field of 4T, so that current in the wire is perpendicular to the magnetic field. The wire is connected to a 10 ohm resistor in series, so that the resistance of the wire is negligible. The wire and resister are then connected in series to a charged 1500mF capacitor at 50 kV. A: What is the current through the wire as function of time, with t-0 being when...
