A circular loop of wire of resistance R = 0.500 2 and radius r = 9.00 cm is in a uniform magnetic field directed out of the page as in the figure below. Bout (a) If a clockwise current of I = 3.40 mA is induced in the loop is the magnetic field increasing or decreasing in time? increasing O decreasing (b) Find the rate at which the field is changing with time. mT/s

A charge moves out of a radiation source with the velocity to the left. Once it enters a uniform magnetic field B it moves upward. What is the type of charge

The device shown in the figure allows you to measure the rate of blood flow in the vessels of the human body, since the blood contains electrically charged ions. Suppose that the blood vessel measures 2.0 mm in diameter, that the magnetic field is 0.080 T and that the fem measurement is 0.10 mV. Is this statement True or False? N S Voltímetro

A circular closed, conducting loop of radius r is in the presence of a uniform magnetic field that points into the page, shown in the figure below. The strength of the magnetic field changes as a function of time, which is described by the following expression: B(t) = B1t? + Bo. You may assume that B1 and Bo are both positive numbers. The direction of the magnetic field stays constant. The total resistance of the conducting loop is R. Use this information to solve parts (a) - (d). Write your answers in terms of known quantities such as: r, R, B1, Bo, and t. B(t) = B,t? + Bo %3D R r (a) Write an expression for the magnetic flux through the loop, assuming that the area vector of the loop points out of the page. Is the flux increasing or decreasing over time? (b) Determine the magnitude of the induced electromotive force driven through the loop. (c) Determine the magnitude of the induced current driven through the loop. (d) In which direction does the induced current flow (clockwise or…
