Alan used a sensor to measure the strength of an electromagnet.He placed the sensor 25 mm from the electromagnet and increased the current in the coil.He repeated the experiment with the sensor 50 mm from the electromagnet.The graph below shows his results.25 mm from electromagnet reading on ...
an electromagnet's strength depends on the amount of current that flows through it. Permanent magnets can lose their magnetic properties such as their ability to give off a magnetic field when they're heated to a certain temperature.
To increase the strength of an electromagnet, you can increase the strength current, and there are several ways to do that. You can also increase the number of windings, lower the ambient temperature or replace your non-magnetic core with a ferro-magnetic material.It...
The outlet of the measuring unit and the outlet of the low-pass element are connected to the signal outlet. An independent claim is also included for a method for determining the magnetic field strength of an electromagnet. Preferred Features: The low-pass element comprises a low-pass element ...
Two additional tests have been performed to check the induced voltages in cases 5 and 6: (i) increasing the field strength by adding additional magnets to the setup, as it was considered that perhaps the field was too weak at the position of the closing wire due to it being further away...
The interaction of M with the applied field causes a repulsive force, repelling the particle away to the direction of a decreasing field strength. If this force balances with the gravitational force, then the particle levitates in the air.2–4 In the case that a material has an anisotropy ...
This immediately tells us that mD should not be far above the TeV scale, because there is a unitarity bound on the strength of the interaction of the Higgs with the fermion [60]. In fact, the entire tower of dyons should have this property! In the limit that the Higgs vev is turned ...
The strength of the interlayer exchange coupling in [Fe/MgO] $$_N$$ (001) superlattices with 2 ≤ N ≤ 10 depends on the number of bilayer repeats (N). The exchange coupling is antiferromagnetic for all the investigated thicknesses while being nine times
The magnitude of the force of magnetic attraction or repulsion depends on the strength of the magnets and the distance between the poles. Examples of known permanent magnet materials include alloys of Neodymium-Iron-Boron (NdFeB), alloys of Aluminum-Nickel-Cobalt (AlNiCo), and Samarium Cobalt (...
