You observe an electron moving on your screen in a clockwise circle of radius 1.25 cm, at a constant speed of 5.67 x 10^6 m/s. Suppose that the electron s circular motion is due to the presence of a uniform magnetic field. What is the magnitude of this magnetic field and what is the direction of the magnetic field?      9.30E-04 T     7.44E-04 T     2.58E-03 T     1.55E-03 T

As shown in the figure below, two long parallel wires (1 and 2) carry currents of I1 = 3.00 A and I2 = 5.10 A in the direction indicated. (a) Determine the magnitude and direction of the magnetic field at a point midway between the wires (d = 10.0 cm). and (b) Determine the magnitude and direction of the magnetic field at point P, located d = 10.0 cm above wire 1.

A beam of electrons moving with speed v = 2.6 × 10’m/s enter and then leave the rectangular region of the magnetic field, as shown below. The trajectory of electrons is a quarter of a circle of radius R= 0.020 m. Mass of electron m = 9.11 x 10-31 kg, charge of electron charge q = 1.6 × 10-19 C).
