The electric field between the plates of a gear selector in a mass spectrometer is 1×105 V/m. The magnetic field of the speed selector is the same as that of the spectrometer. A beam of +e charged neon ions leaving the speed selector moves in a circular path in the spectrometer before hitting the photographic plate. After a certain time, three spots are observed at distances of 7.4 cm, 7.8 cm and 8.15 cm, respectively.

- A velocity selector is tuned to allow an electron with a speed of 280279 m/s through with no deflection. It used a magnetic field of 7.8 mT. What is the magnitude of the electric field (in V/m) being used?An electrocardiogram (ECG) measures electric activity of neurons in the brain. Electroencephalograms and electromyograms respectively measure similar activity over the scalp and over the skin surrounding muscle cells. Because the electrical activity of the human body varies with time, the time-varying electric fields in the body lead to the generation of magnetic fields that can then be measured. The magnetocardiogram, developed in the 1960s, was the first such device. More recently, superconducting quantum interference devices (SQUIDS) have been used for these measurements. One important application of this technique is the monitoring of the fetal heart by measuring the magnetic field produced by currents in the heart at the surface of the mother's abdomen. The fetal heart at 28 weeks gestation can be modeled as a single-loop coil 1.50 cm in diameter, oriented so that the plane of the loop is parallel to the abdominal surface of the mother, and a magnetic field of 10.0 pT is typically…A singly charged positive ion has a mass of 5 kg.
