In the situation below a wire carrying a current I is near a square loop of wire also carrying a current in the counter-clockwise direction. The vertical wire is stationary. Which of the following are true about the motion of the loop of wire? y O there is a torque about the x-axis O there is a torque about the z-axis O the answer depends on L O there is a net force to the right O there if a net force upward O there is a net force to the left O there is a net force out of the page O there is a torque about the y-axis O there no net force and no torque O there is a net force into the page O there is a net force downward

The following represents an electromagnet. What are three way one could increase the strength of an electromagnet? iron nail Battery coil wire coil of increase the current, deccrease number of coils, add iron to the core O deccrease the current, increase number of coils, add iron to the core O increase the current, increase number of coils, add iron to the core O Use alternating current, add iron to the battery, add a transformer

The image below shows two bar magnets that are fixed in place (they can't move). There is a proton moving E, that is just about to enter the magnetic field. Which one of these statements best describes the motion of the proton while it is between the magnets? (a) proton continues to move right in a straight line (b) proton curves down, and hits magnet (c) proton stops and moves left (d) proton curves up and hits magnet

Two long, straight wires are parallel and 5 cm apart. One carries a current of 2.0 A, the other a current of 5.0 A. If the two currents flow in opposite directions, what is the magnitude and direction of the force per unit length of one wire on the other?    a) 4.00e-5 N/m Away from each other b) 1.67e-5 N/m Towards each other c) 4.00e-5 N/m Towards each other d) 1.67e-5 N/m Away from each other
