Can the Earth's magnetic field affect experimental measurements of magnetic field in coils?

In an experiment, the magnetic field B of a large coil was measured using a small coil. Can the Earth's magnetic field affect the observed measurements of B? If so, how would it affect the signals experimentally measured from the small coil?

Answer #1

This seems like an experiment based question.

Generally, magnetic field of earth will not have any effect on the experimental results because the magnetic field on the surface is not so strong due to large distance between earth's center and surface.

Therefore, the strength of earth's magnetic field is not strong enough to overcome the large distance between the center of the earth and experimental setup making the effects of the Earth’s magnetic field negligible.

You are performing studies of the possibility of migrating birds using the Earth's magnetic field for navigation. To modify the magnetic field in the brain of a bird, you fit the bird with coils as "caps" and "collars" as shown in the figure below. The illustration shows a bird with a long neck floating in water with metal coils fitted around its head and neck. The "cap" coil rests on top of its head like a crown. An identical second...

17.1) Helmholtz coils The magnetic field on the axis of a circular loop of wire is not very uniform (in fact, we showed that the field strength decreases as 1/r3 ). But, with two such coils, one can produce a relatively uniform field in a small neighborhood. Consider two parallel circular coils of radius a, centered on the y-axis. One coil is in the y = 0 plane, and the other is in the y = d plane. Assume that...

Helmholtz coils are frequently used in experiments because they create a uniform magnetic field about their axial direction. For example, they are traditionally used in the experiment for the measurement of the charge to mass ratio of the electron. Helmholtz coils are two coils separated by a distance equal to their radius and also carry equal currents in the same direction, as shown in the figure on the right. Suppose the radius of the coils is 12.00 cm, each coil...

Helmholtz coils are a method developed to provide a uniform magnetic field in a small region. They are constructed by placing two identical wire loops parallel to each other, separated by a distance equal to their radii, as shown in the Figure. Assume that the two loops are also connected in parallel to a power supply, so that they produce the same field. (a) Find the length of a 28-gauge copper wire that will produce a 75 Ω coil. m...

A circular loop with 50 coils is pulled (to the right) from an external magnetic field of 0.8 T into the page. At t=0 the right edge of the loop is at the right edge of the magnetic field. After 0.250 seconds the loop has moved completely out of the magnetic field. Diameter of the coil is 10 cm Find the rate of change in flux through one loop as the loop if the loop is pulled out of the...

The earth's magnetic field, with a magnetic dipole moment of 8.0×1022Am2, is generated by currents within the molten iron of the earth's outer core. Suppose we model the core current as a 3000-km-diameter current loop made from a 1000-km-diameter “wire.” The loop diameter is measured from the centers of this very fat wire. A)What is the current in the current loop? B)What is the current density J in the current loop? C)To decide whether this is a large or a...

1. The magnetic field at the earth's surface can vary in response to solar activity. During one intense solar storm, the vertical component of the magnetic field changed by 2.8 μT per minute, causing voltage spikes in large loops of the power grid that knocked out power in parts of Canada. Part A) What emf is induced in a square 110 km on a side by this rate of change of field? 2.What is the magnetic field amplitude of an...

What are Helmholtz coils used for? What quantities does the strength of the magnetic field B produced by the Helmholtz coils depend on? Which can be varied? What affect does the Lorentz force have on the motion of electrons? The beam of electrons you will observe is more like a thin ring, with a width. Are the electrons all moving at the same velocity? If not, are the electrons on the outer edge of the beam or the inner edge...
