    behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found evidence that magnetic field lines go from a north magnetic pole to a south magnetic pole. These results were seen in all three magnetic devices. When determining the magnitude of the electric field in the Helmholtz coils

    interaction is described in terms of a vector field‚ where each point in space (and time) is associated with a vector that determines what force a moving charge would experience at that point (see Lorentz force). Since a vector field is quite difficult to visualize at first‚ in elementary physics one may instead visualize this field with field lines. The magnetic flux through some surface‚ in this simplified picture‚ is proportional to the number of field lines passing through that surface (in some

    Assignment View] [ Print ] Electric Field Due to Increasing Flux Learning Goal: To work through a straightforward application of Faraday’s law to find the EMF and the electric field surrounding a region of increasing flux Faraday’s law describes how electric fields and electromotive forces are generated from changing magnetic fields. This problem is a prototypical example in which an increasing magnetic flux generates a finite line integral of the electric field around a closed loop that surrounds

    qualitiviely analyze principles of magnetic fields and forces‚ their sources‚ and interactions with moving charged particles. To accomplish this lab‚ we will do 5 stations‚ and we need these instruments: several magnets which have different sizes‚ a board‚ a piece of alumium metal‚ a battery‚ two pieces of wires‚ a nail‚ a 180cm copper pipe. Station1‚ we tilt a smooth board and roll the neodymium down it‚ the track is curve because the magnetic field of the earth is affecting the magnet. The effect
