In a physics laboratory experiment, a coil with 150 turns enclosing an area of 11.4 cm2 is rotated in a time interval of 3.50×10−2 s from a position where its plane is perpendicular to the earth's magnetic field to one where its plane is parallel to the field. The earth's magnetic field at the lab location is 6.2×10−5 T. What...
If you can, please answer both questions! Thank you! 1. A wire carries a current of 0.50 A. This wire makes an angle of 61° with respect to a magnetic field of magnitude 7.0 × 10-5 T. The wire experiences a magnetic force of magnitude 8.0 × 10-5 N. What is the length of the wire? 2. A charged particle...
below is the hint from my professor for the solution
hopefully it can help you guy for the solving problem

Three identical charged spheres are put at the corners of a square with only one sphere at each corner, leaving one corner "empty". The charge of each sphere is 3.40 µC. The side length of the square is 3 m. What is the magnitude of the electric field at the "empty" corner? _________N/C
PLEASE MAKE ANSWER CLEAR AND LEGIBLE!!!
Question:
In this quiz, you will examine the behavior of a simple motor speed con- trol system. Figure 1 shows the block diagram of the entire control loop Without covering the details, the motor is approximated by two equations First, the current through the motor coils (IM) creates a magnetic torque TM. We consider...
