WebRemember to use Fleming’s left-hand rule to obtain the direction the electrons move due to the magnetic force created by the magnetic field. USING A HALL PROBE. Measuring Magnetic Flux Density using a Hall Probe. A Hall probe can be used to measure the magnetic flux density between two magnets based on the Hall effect WebNov 16, 2024 · The term magnetic force refers to forces that do not exist because they do not touch objects. Although magnets are attracted to a specific group of’magnetic’ metals, they don’t always like everything. One of the rarest and most versatile natural materials is a magnet, which can exert control over other objects without physically touching them.

WebThus the rate of change of the magnetic flux is. Δ Φ Δ t = Δ ( B A cos θ) Δ t = B Δ A Δ t = B v ℓ, 20.34. where we have used the fact that the angle θ between the area vector and the magnetic field is 0°. Once we know the emf, we can find the current by using Ohm’s law. WebIf we want the door to require 10 lb of shear force to open it, we’re going to have 20 lb of attraction between the magnets. This places a big load on the hinge and door frame. It’s like hanging a 20 lb bag of groceries on the doorknob. This didn’t matter much on the full-size door we tested.
