The magnetic flux value depends on the magnetic field direction and it is a vector quantity. Θ = Angle between the magnetic field and normal to the surface. The Dimension of a rectangular loop is 0.50m and 0.60m. B and θ are 0.02T and 45° respectively.

If a car is traveling on the highway at a constant velocity, the force that pushes the car forward must be a. equal to the weight of the car. b. less than the force of friction exerted upon the car. c. equal to the force of friction exerted upon the car. d. greater than the weight of the car.
