An MRI (magnetic resonance imaging) solenoid produces a magnetic field of 1.5T. The solenoid is 2.5m long, 1.0m in diameter, and wound with insulated wires 2.2mm in diameter. Find the current that flows in the solenoid (Your answer should be rather large.)

In magnetic resonance imaging (MRI), a patient lies in a strong 1- to 2-TT magnetic field B⃗ B→ oriented parallel to the body. This field is produced by a large superconducting solenoid. The MRI measurements depend on the magnetic dipole moment μ⃗ μ→ of a proton, the nucleus of a hydrogen atom. The proton magnetic dipoles can have only two orientations: either with the field or against the field. The energy needed to reverse this orientation ("flip" the protons) from...

Magnetic resonance imaging, or MRI, and positron emission tomography, or PET scanning, are two medical diagnostic techniques. Both employ electromagnetic waves. For these waves, find the ratio of the MRI wavelength (frequency = 6.92 107 Hz) to the PET scanning wavelength (frequency = 1.23 1020 Hz).

Chapter 22, Problem 20 Magnetic resonance imaging (MRI) is a medical technique for producing "pictures" of the interior of the body. The patient is placed within a strong magnetic field. One safety concern is what would happen to the positively and negatively charged particles in the body fluids if an equipment failure caused the magnetic field to be shut off suddenly. An induced emf could cause these particles to flow, producing an electric current within the body. Suppose the largest...

You are designing a solenoid to produce a 2.7-kG magnetic field. You wish to wrap your insulated wire uniformly around a cardboard tube that is 8.0 cm in diameter and 53 cm in length, and you have a power supply that will allow you to pass a current of 2.5 A through the solenoid. Determine the total length of wire you will need in order to build the solenoid you have designed.

The strength of the magnetic field within a solenoid is B = 2.1 × 10-2 T (outside the solenoid B = 0). A smaller, single loop is placed in the solenoid parallel to the plane of each loop in the solenoid. The resistance of the solenoid is 5.9 W, the resistance of the loop is 0.27 W, the diameter of the solenoid is 0.09 m, and the diameter of the loop is 0.05 m. An emf of 12 V is...

If you pass a current through a wire, you can create a magnetic field. In this class we examine the field from three specific configurations: an infinitely-long straight wire, a compact loop of wire (possibly with multiple turns, a coil), or an infinitely long solenoid (think of an infinitely-long cylinder of loops made by wrapping a single wire). See the text for an extended description of all three geometries. Here’s the challenge: there are three slightly different formulas used to...
