MAGNETIC FIELDS SUMMARY You will measure how the magnetic field, B, produced by a coil varies with the current, I, in the coil. From your measurements, you w calculate the permeability constant Ho. Lastly you w use a magnet to induce a voltage in the coil. THEORY The magnetic field Batthe center of a circular coil (solenoid) of radius R with N turns that carries a current...

1. In a region of space free of currents, the electric and magnetic fields at t 0 are determined to be: where a is a constant and is a unit vector in the y-direction. (a) What is the charge density at t-0, p(F,0)? (b) Caleulate the magnetic field as a function of tme (c) Calculate the electric field as a function of time

1. Which statement about the nature of electric and magnetic fields is the most accurate? A)Fields can only ever be "electric" or "magnetic", regardless of reference frame. B)Whether a field is seen as "electric" or "magnetic" depends on the motion of the reference frame relative to the sources of the field. C)"Electric" and "magnetic" fields are entirely unrelated.

This question focuses upon the fields arising from currents in straight wires. When providing numerical answers you may express them using scientific notation. Unless stated otherwise, express values to four significant figures and use the values of physical constants as provided in the course notes.

Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...

Using magnetic and electric fields, you want to create a spectrometer to sort isotopes of hydrogen ions. A stream of 1H, 2 H+, and > H+ are accelerated to 2.00x105 m/s and launched into a velocity selector in a region where you can establish a uniform magnetic field with a strength of 240 mt. What electric field will you need to see that only ions with this speed make it into the spectrometer? How far away from the entrance to...
