Magnetic flux density vs magnetic flux - Physics Forums
2010年3月1日 · FAQ: Magnetic flux density vs magnetic flux What is the difference between magnetic flux density and magnetic flux? Magnetic flux density, also known as magnetic field strength, is a measure of the strength of a magnetic field at a given point. It is represented by the symbol B and is measured in units of tesla (T).
Calculating the flux density between two magnets - Physics Forums
2020年1月28日 · The flux density between two magnets can be calculated using the formula B = μ0 * (m1 * m2)/(4 * π * d^3), where B is the flux density, μ0 is the permeability of free space, m1 and m2 are the magnetic moments of the two magnets, and d is the distance between them.
Why a magnetic flux in closed surface area is always 0? - Physics …
2008年1月17日 · In summary, the magnetic flux through a closed surface is always zero due to the fact that magnetic monopoles do not exist. This is one of Maxwell's equations and is in contrast to Gauss's law for electric fields. In the case of …
Magnetic Flux through a Cylinder - Physics Forums
2007年3月21日 · The magnetic flux through a cylinder is affected by the strength and direction of the magnetic field, the size and orientation of the cylinder, and the material of the cylinder. The magnetic permeability of the material, which is a measure of how easily a material can be magnetized, also plays a role in determining the magnetic flux.
Magnetic flux with non-uniform magnetic field - Physics Forums
2010年11月13日 · Magnetic flux with non-uniform magnetic field is calculated by taking the dot product of the magnetic field vector and the surface area vector. This can be represented mathematically as Φ = ∫B⋅dA, where Φ is the magnetic flux, B is the magnetic field, and dA is the differential surface area.
Shielding a wire from magnetic flux - Physics Forums
2019年2月20日 · Magnetic flux is the measure of the strength of a magnetic field passing through a given area. Why do we need to shield wires from magnetic flux? Shielding wires from magnetic flux is important because it can cause interference and disrupt the flow of electricity in the wire, leading to malfunctions or errors in electronic devices.
Why Is It Sin Theta Instead of Cos Theta in Magnetic Flux …
2017年5月19日 · How does the angle for magnetic flux affect the amount of induced current? The angle for magnetic flux is directly proportional to the amount of induced current. This means that the larger the angle, the less current will be induced, and vice versa. This is known as Faraday's law of induction. Can the angle for magnetic flux be changed? Yes ...
Magnetic Flux in a Coaxial Cable - Physics Forums
2016年5月5日 · Yes, the magnetic flux in a coaxial cable can be controlled by using materials that have high magnetic permeability, such as iron or ferrite, to shield the cable from external magnetic fields. Additionally, using twisted pairs or braided shielding can also help reduce the effects of magnetic flux on the cable's performance.
