1. Calculate the magnetic field of a straight wire which is made as a circular loop
with a radius of 0.1m. The current flowing through this dosed loop is given as
5amp?
2. An electron is moving to the east at a speed of 1.8x10%m/s. It feels a force in the
upward direction with a magnitude of 2.2x10-12N. What is the magnitude and
direction of the magnetic field this electron just passed through?
3. A wire 0.10 m long carries a current of 5.0 A. The wire is at right angles to a uniform
magnetic field. The force the field exerts on the wire is 0.20 N. What is the magnitude
of themagnetic field?
