A square coil and a rectangular coil are each made from the same length of wire. Each contains a single turn. The long sides of the rectangle are twice as long as the short sides. Find the ratio Tsquare/Trectangle of the maximum torques that these coils experience in the same magnetic field when they contain the same current. Number Units

A 180 turn solenoid having a length of 24 cm and a diameter of 9.5 cm carries a current of 0.29 A. What is the magnitude u of its magnetic dipole moment? Number i Units eTextbook and Media

Write a word problem with the picture below. You can pick your own numbers and find the radius or the distance of the helical coil or the electric force or magnetic force.

Magnetic Field in a Current Loop You have a current loop with 21.00 loops. You measure the magnetic field at the center and find a result of 6.60 µT. The current in the loops (each individual wire) is 1.780 A. What is the radius of the loop? Your Answer: Answer units

At a certain location, the horizontal component of the earth's magnetic field is 2.1 × 10-5 T, due north. A proton moves eastward with just the right speed, so the magnetic force on it balances its weight. Find the speed of the proton. Number i Units

Please solve the question correctly and also be sure to give the correct units. Thank you!

Magnetic Field in a Toroid You have a toroid with 21.00 loops and a current 0.560 A. You measure the magnetic field at a distance r from the center of the toroid and find a result of 7.30 UT. What is the value of r (distance from the center of the toroid)? Your Answer: Answer units

Figure shows four particles moving to the right as they enter a region of uniform magnetic field, directly into the page. All particles move at the same speed and have the same charge.  Which particle has the least mass?

Three particles with the same magnitude charge are shot with the same speed into a uniform magnetic field. Which particle(s) has/have the largest mass? A

A current of IL = 0.10 A runs clockwise in a loop forming the figure shown below. A uniform magnetic field magnitude B=0.007 T points to the left. 5. L, = 0.020 m L4 0.050 m L, = 0.030 m B L3 = 0.060 m a) Find the force on each segment, giving both an expression or value for the magnitudes the directions shown on the diagram. Use arrows for any forces in the plane of the page and dots and x's for any forces out of and into the page, respectively. b) Find the direction (if there is a force) and the magnitude of the net force on the loop (numbers or expressions for magnitude.) c) Find the direction (if there is a torque) and magnitude of the net torque (numbers or expressions for magnitude, vector direction or rotation sense for torque if there is a torque.)
