The Strength of the Magnetic Field and the Magnitude of the ForceĪim: To investigate the relationship between the strength of the magnetic field and the magnitude of the force on a conductor. The magnitude of the force on a current-carrying conductor in a magnetic field increases when the current increases. The magnitude of the force increases when the current is increased.The height of the swing, h increases when the current in the copper frame is increased. This force causes the frame to swing upwards. The interaction between this magnetic field and the magnetic field from the magnadur magnets produces a force on the copper frame. The current in the copper frame produces a magnetic field.The rheostat is adjusted to minimum resistance so that the current is maximum and step 3 is repeated.The height of the swing, h of the copper wire frame is measured with a half-metre rule. The rheostat is adjusted to maximum resistance so that the current is minimum.The apparatus is set up as shown in Figure.power supply, rheostat, retort stand with clamp, half-metre rule 26) with bare ends, a pair of magnadur magnets with U-shaped steel yoke, connecting wiresĪpparatus: d.c. 20 or thicker) with bare ends, thin insulated copper wire (s.w.g. Materials: A block of wood, thick insulated copper wires (s.w.g. Operational Definition: The height of the swing, h of a copper wire frame represents the magnitude of the force acting on it. (c) Fixed variable: The strength of the magnetic field (b) Responding variable: Magnitude of the force on the conductor Hypothesis: The greater the size of the current, the greater the magnitude of the force. Inference: The current affects the magnitude of the force on a current-carrying conductor.
