Electromagnetic: Force on Conductors in Magnetic Fields - Lab Report Example

Electromagnetic: force on conductors in magnetic field al affiliation) Introduction Magnetic force acting on a current can be established by adding the magnetic force acting on each charge that contributes to the current. When an electric wire is exposed to a magnet, the current being carried in the wire will be affected by a magnetic field. The consequence often comes in form a force. The magnetic force expression can be identified by summing the magnetic force on each charge. The forces can often be added given that they all run in one particular direction. The paper is discussion on the force of conduction in a magnetic field. The aim of the experiments conducted is to determine the relationship between force and various parameters such as the length of the conductor, the strength of the field, the angle between the current and the field and the strength of the current. Methodology The experiment utilized a current balance that was set using a set up that will be made up of an arm, stand, Coil, or PCB, balance, two types of magnet and a power supply (5A). When current coming from the power supply is passed into the circuit board that is sitting on magnetic field being generated by the magnets, the force created is transferred to the balance. The force can often be determined though adjusting the balance to measure the effective weight. The method was to fix three parameters to the principles provided. In addition, measure the force while varying each of the parameters as well as plot the variation of the force against the parameters. The current was to be adjusted on the power supplied by utilizing the limiting facility of the current supplied. The voltage control should be adjusted to 5V, the DC output should be short circuited with one of the leads, the maximum current should be set to 1amp by utilizing the current adjust control, the short circuit should be removed, the circuit for the experiment should be well connected with the chosen current set by utilization the current adjust control. The voltage control should not be changed.

In situations where the length of the conductor is doubled and the magnetic field is halved, the overall force experienced by the system often remains unchanged. Moreover, if the angle of orientation is varied from zero degrees to forty five degrees, the force of the overall system will be increased. A voltmeter and a loudspeaker are the two examples of electrical machine that utilizes force on conductors in magnetic fields. A loud speaker often produces sound that acts as a response to an electrical audio signal with the voltmeter measuring the voltage change between two points in a circuit. Conclusion A current carrying wire placed in the magnetic field often experiences a force as a result of interactions between the moving charges and the magnetic field. The force of the current is often influenced by the length of the conductor in the field, the current on the wire, the sin of the angle theta as well as the strength of the field.
