Suppose you wish to produce a 1-T magnetic field in a toroid with an iron core for which magnetic susceptibility is x = 3 x 10³. The toroid has a mean radius of 14 cm and is wound with 600 turns. Hint a. What current is required to produce this magnetic field in the iron core? Current of b. For comparison, what current is required to produce the same magnetic field in an air-filled toroid of same geometry? Current of A is needed. Submit Question A is needed for toroid with no iron core. While it is not always practical to have region of magnetic field filled with ferromagnetic materials, this dramatic increase in strength of magnetic field produced is useful in some applications you will see in upcoming chapters.

Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field acting perpendicularly to its axis of rotation. Coil 1 has a radius of 4.6 cm and rotates in a 0.21-T field. Coil 2 rotates in a 0.54-T field. Each coil experiences the same maximum torque. What is the radius (in cm) of coil 2? Number i Units

Consider two parallel wires carrying current in the same direction. Which one of the following statements is true concerning this situation? O The two wires will repel each other, even no external magnetic field is applied to the wires. O The two wires will repel each other, only if an external magnetic field is applied to the wires. O The two wires will attract each other, even if no external magnetic field is applied to the wires. O The two wires will attract each other, only if an external magnetic field is applied to the wires. The wires will be neither attracted nor repelled from each other regardless of whether or not an external magnetic field is applied to the wires.
N batteries not shown A. A wire is connected to batteries (not shown), and current flows through the wire. The wire lies flat on a table, and you are looking down on it from above. The wire is laid on top of a compass, resting about 6 mm above the needle. The distance d is 5.5 cm. The compass needle deflects 11 degrees from North, as shown. At this location the horizontal component of the Earth's magnetic field is 2e-5 tesla. What is the direction of the magnetic field at location A, midway between the wires, due to the current in the wire? Out of the page What is the approximate magnitude of the magnetic field at location A, due to the current in the wire? |B| = 3.88e-6 × T What approximations or assumptions did you make in solving this problem? Assume one side of the wire is much longer than d Assume that at the location of the compass the effect of the distant wire is negligible Assume the Earth's magnetic field is negligible Assume the bent end of the wire is far from location A
