WebbMagnetic Field Created by a Long Straight Current-Carrying Wire: Right Hand Rule 2. Magnetic fields have both direction and magnitude. As noted before, one way to explore the direction of a magnetic field is with compasses, as shown for a long straight current-carrying wire in Figure 22.37. Hall probes can determine the magnitude of the field. http://www.gcsescience.com/pme1.htm
WebbThe Biot - Savart Law (5) (a) A conducting loop in the shape of a square of edge length l = 0.400 m carries a current I = 10.0 A as shown on Figure. Calculate the magnitude and direction of the magnetic field at the center of the square. (b) What If? Webb14 nov. 2024 · When two conductors carry currents in opposite directions, the effect on the fields is shown in Figure 3 (a). The directions of the magnetic fields around the …
WebbIn fact, the field around the wire is circular in shape; the needles of the plotting compasses form a continuous loop around the wire. These circles stretch out along the wire, forming cylinders. If an electric current is passed through a long coil of wire (a solenoid) a magnetic field is produced which is the same shape as that of a bar magnet. WebbPhysicists use a hand mnemonic known as the right-hand rule to help remember the direction of magnetic forces. To form the mnemonic, first make an L-shape with the …
