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 surface of the body...

The drawing shows a straight wire carrying a current I. Above the wire is a rectangular loop that contains a resistor R. If the current I is decreasing in time, what is the direction of the induced current through the resistor R — left-to-right or right-to-left? If the induced current goes from left to right through the resistor, type the letters "LTR" in the box below. If the current goes from right to left through the resistor, type the letters...

Jose needs an MRI (magnetic resonance imaging) scan. During the exam, Jose lies in a region of a very strong 1.7-TT horizontal magnetic field pointing from Jose's waist toward his head. A medical assistant moves Jose from the scanner, reducing the magnetic field from 1.7 TT to 0.1 TT in 1.0 ss. Consequently, the B⃗B→ field through Jose's 0.30-mm by 0.40-mm chest decreases. The conductive tissue inside his body around the outer part of his chest is a loop, with...

A patient is having a magnetic resonance imaging scan (an MRI) and has neglected to remove a 7.3 cm diameter metallic bracelet. The resistance of the bracelet is 0.0130 2. The magnetic field within the MRI's solenoid is perpendicular to the opening of her bracelet. While taking the scan, the magnetic field decreases from 1.09 T to 0.45 T in 1.50 seconds. What is the magnitude of the average induced voltage in the bracelet? 4.20*10^-3V Submit Answer...
A conducting rod is being dragged along conducting rails, as shown in (Figure 1)
Part A A conducting rod is being dragged along conducting rails, as shown in (Figure 1). The magnetic field is directed out of the screen. In what direction does the induced current flow through the light bulb? There is no induced current. The induced current flows through the bulb from the left to the right. The induced current flows through the bulb from the right to the left. Part B A circular loop of conducting wire is moving through a uniform magnetic field, as...
Two parallel lengths of wire are separated by 10 cm and connected at the left edge by a 160 resistor
Two parallel lengths of wire are separated by 10 cm and connected at the left edge by a 160 resistor. A conducting bar rests on the wires, perpendicular to both, and is pulled to the right at 12 m/s. A magnetic field of 2.2 T points into the page through the coll, such that the magnetic field is perpendicular to the plane of the loop. a) What is the emf induced in the loop? b) What is the current in the loop?c)...

Hi! Please help solve for questions 5 and
6! Thank you so much
The figure below shows two infinitely long, straight, current-carrying wires located at x = -20.0 cm and at x = +30.0 cm. The left-hand wire carries current z direction (into the page), and the current I_2 in the right-hand wire is unknown. If the magnitude of the total magnetic field due to the two wires at the origin is 3.60 mu T, what are the two possible...

In a region with a constant magnetic field as shown, there are
two conducting frictionless horizontal rails, a resistor and some
conducting wire along the left side and a conducting bar on the
right side that is free to slide left or right. The bar is
initially at rest but at time zero a force is applied to the bar
pulling it to the right so that the distance s increases with
time.
