If the direction of a magnetic field around a straight wire is counterclockwise, which direction is the current traveling?An electron moving along the positive x axis perpendicular to a magnetic field experiences a magnetic direction in the negative y direction. What is the d...
is a measure of thestrength of the magnetic field. Specifically, 1 Gauss is equivalent to 1 magnetic field line within 1 square centimeter.Also, the direction of the tangent to the field line is the direction of the magnetic field at that point and is the direction a compass would point....
Thus the reason a compass needle points in the direction humans have labeled "magnetic north" is that the needle is compelled to orient itself in the same direction as Earth's magnetic field, owing to a shift in the electrons in the atoms of the needle's material in response to the field...
Ferrimagnetism: Like ferromagnets, ferrimagnetsretain magnetizationwhen removed from a magnetic field but neighboring pairs of electron spins point in opposite directions. The lattice arrangement of the material makes the magnetic moment pointing in one direction stronger than that pointing in the other d...
According to van Bemmelen's investigation, contained in this number of the Journal, it would appear that since about 1840 the northern end of his mean magnetic axis of the Earth, deduced from magnetic declinations alone, has been moving in a northwest direction, i.e., increasing its north ...
magnets. The reading of the flux meter is related to the position of the sample in the measuring coil. The calibration of the test coil requires a constant current to test the size of the magnetic field in a zero magnetic field environment, and then the constant of the test coil is ...
Did you know that magnetic compass does not always point to North? Actually, there are only a few locations on Earth where it points exactly to the True (geographic) North. The direction in which the compass needle points is known as Magnetic North, and the angle between Magnetic North and...
A magnetic pole is the point of on one end of the magnet where the magnetic force is focused. The magnetic field is strongest at this point. There...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
The strength of a dipole is measured as the magnetic. The moment is a vector, meaning it has a magnitude, or size, as well as a direction. When considering magnetic poles, such as those in a bar magnet, the magnetic moment (m) is defined as the strength of the poles (p) multiplied...
24. In what direction will the magnetic field lines point in the region just outside the south pole?B A. Go around the south pole B. Point toward the south pole C. Point away from the south pole D. Are less concentrated than at the north pole 相关知识点: 试题来源: 解析 B 反...
