Why do we only see a small portion of the earth’s magnetic field?
help please 2. Why do we see that each cell is only expressing a small fraction of the genes in it's genome at any given time?
Electrons in Earth’s magnetic field orbit with a frequency of 1.4 MHz. At what frequency do tau particles orbit? Tau particles have the same charge as electrons, but they are 3360 times more massive than electrons.
You want practically no magnetic field in a small region of space, not more than 10% of Earth’s magnetic field at that location. The Earth’s magnetic field line is angled downward 72.7 degrees into the earth but practically due north. The field strength is 55.66 microTesla a. Take a single wire and make a loop with it with a radius of 80 cm. Put your small apparatus right at the origin of this loop. This will work because it is...
The earth’s magnetic field is approximately 0.000050 T. What is the energy in 1.1 m3 of that field? x 10-3
At a location near the equator, the earth’s magnetic field is horizontal and points north. An electron is moving vertically upward from the ground. What is the direction of the magnetic force that acts on the electron? (a) North (b) East (c) South (d) West (e) The magnetic force is zero.
For the setup below, we can see that coil A will generate a magnetic field that coil B will see. As long as the field is constant, no induced magnetic fields will be produced by coil B. However, if the field from A changes, then coil B will induce a voltage which induces a current which induces a magnetic field to oppose any change. So what will be the direction of the current if: The switch on A is opened...
#2 near the ground at the north magnetic pole, the earth’s magnetic field is directed downward vertically and has a strength of 0.57 G. An electron at the north pole is projected from the ground into this magnetic field with a velocity of 1.4 km/s vertically upward and 1.9 km/s horizontally to your right. A) find the magnitude of the force acting on this electron B) find the electron’s acceleration (magnitude and direction)
the earth’s magnetic field is about 50 µT, at a 60° dip angle. If your textbook is resting on the table, what is the downward flux through the cover of the book?
A proton in the Solar wind strikes the Earth’s magnetic field at a right angle with a velocity of 2.75 x 105m/s. If the field has strength of 4.33 x 10-5T and the Lorentz force acts to move the proton in a circle, what’s the radius of this circle? A) 0.0589m B) 6.08 x 1019m C) 2.64 x 10-10m D) 66.3m
A cosmic-ray electron moves at 7.0 × 106 m/s perpendicular to Earth’s magnetic field at an altitude where the field strength is 0.5 × 10−5 T. What is the period of revolution of electron? in microseconds.
