A rectangular coil of wire, 22cm by 35 cm and carrying a current of 1.4A, is oriented with the plane of its loop perpendicular to a uniform 1.5T magnetic field.

a) calculate the net force and torque which the magnetic field exerts on the coil.

b)the coil is rotated through a 30 degree angle about the y axis, the left side coming out of the plane. Calculate the net force and torque which the magnetic field now exerts on the coil

Two spherical objects are separated by a distance of $1.80\times {10}^{\xad-3}$ m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of $4.55\times {10}^{-21}$ N. How many electron did? It take to produce the chargeon one of the objects?

A proton is released in a uniform electric field, and it experiences an electric force of $3.75\times {10}^{-14}\text{}N$ toward the south. What are the magnitude and direction of the electricfield? The equation is E=f/q, but there is only one number and three variables. What numbers go in the other two?

Three identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force $\overrightarrow{F}$ The magnitude of the tension in the string between blocks B and C is T=3.00N. Assume that each block has mass m=0.400kg.

What is the magnitude F of the force?

What is the tension in the string between block A and block B?

Electromagnetism Physics belongs to those aspects of the science that can be applied to anything from engineering to design and construction of automation for our daily life. Since we are dealing with the relations between electricity and magnetism, finding answers and questions that we present will help you to see practical examples like radio, gamma rays, or microwave emissions. Take at least one electromagnetism example and you will be able to repeat the steps or receive relevant help. Make sure to focus on the experiments and the order of the steps to gain even more clarity as you study electromagnetism.
