The light beam from a searchlight may have an electric-field magnitude of 1000 V/m, corresponding to a potential difference of 1500 V between the head and feet of a 1.5-m-tall person on whom the light shines. Does this cause the person to feel a strong electric shock? Why or why not?

Magnetic Force

A magnetic force arises when a charged particle or a current-carrying conductor is placed in a magnetic field. It is created because of the movement of the charged particles.

The figure below shows a mass spectrometer. Particles with charge -e = -1.60×10^−19 C enter a "velocity selector" with a magentic field of 0.0053 T (into page). The velocity selector also contains an electric field (90,000 V/m) pointing down as shown. In the velocity selector only passes particles that experience no NET force. These particles have a velocity set by the magnitude of the E and B fields in the velocity selector. These particles then leave the velocity selector and enter a region with a magnetic field that has a strength of 0.00242 T, into the page 1)If the radius of curvature of the particle is 4.00 cm, use the information in this problem to calculate the mass of the particle. Hint, first compute the velocity of particles that experience no net force in the velocity selector. Use this velocity and the information given to compute the mass of the particles. (Express your answer to two significant figures.)

The top of the atmosphere is at about 400 kV with respect to the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100 Vm-1 Why then do we not get an electric shock as we step out of our house into the open? (Assume the house to be a steel cage so there is no field inside!)
With each beat, the human heart generates a electromagnetic field, and the potential difference (voltage) oscillates over the course of each beat cycle. So, like an antenna, the human heart generates an electromagnetic wave. An electrocardiogram (EKG) is a medical diagnostic tool that measures the voltage (difference) between electrodes that are attached to different parts of your body, producing a chart that (hopefully) looks like the rhythmic pulses shown in figure. An EKG reveals that your heart is beating 72 times a minute, and that each beat generates a maximum potential difference, Vmax = 3.5-mV, across the 0.35-m width of your chest cavity. Use &o = 8.854 x 10-12 Nm²/C², Ho = 4 x 10-7 Tm/A, and c = 2.998 x 108 m/s.

A surgeon is attempting to measure the speed of blood flow in an aorta (a blood vessel) prior to surgery. The surgeon applies a 2.33 Tesla B-field perpendicular to the flow of blood. A little while later they measure the potential difference across the walls of the aorta and then estimate from that measurement that the blood is flowing at 90 cm/s. Suppose that the aorta has a radius of 1.32 cm. What potential difference (in Volts) did the surgeon notice (measure) to make the above speed estimation? Potential difference across the aorta = I V
