How can you calculate change in magnetic flux? - Physics Forums
2005年4月3日 · Since the magnetic flux is completely perpendicular to the loop, the magnetic flux at anytime is B*A, where A is only the area that is within the magnetic field. Magnetic flux = B*A you can differentiate this equation with respect to time to find the rate of change of flux, and relate dA/dt to the information given in the question.

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 density vs magnetic flux - Physics Forums
2010年3月1日 · Magnetic flux density and magnetic flux are related by the equation B = Φ/A, where A is the area through which the magnetic field is passing. This means that the magnetic flux density is directly proportional to the magnetic flux and inversely proportional to the area.
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.
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.
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.
What is the Magnetic Flux Exiting a Cube? - Physics Forums
2014年7月10日 · How is magnetic flux calculated? Magnetic flux is calculated by multiplying the magnetic field strength (in Tesla) by the area through which it is passing (in square meters). This can be represented by the equation Φ = B * A. What is the unit of measurement for magnetic flux? The unit of measurement for magnetic flux is the Weber (Wb).
Why Is It Sin Theta Instead of Cos Theta in Magnetic Flux …
2017年5月19日 · Why is the angle for magnetic flux important? The angle for magnetic flux is important because it determines the strength of the magnetic field acting on a surface or object. A larger angle means a weaker magnetic field, while a smaller angle means a stronger magnetic field. How does the angle for magnetic flux affect the amount of induced ...
