Sources of Magnetism: Exploring the Fundamentals This presentation explores the fundamental principles of magnetism, examining how it arises from electric currents and exploring its diverse applications. by Geraldine Neri preencoded.png Magnetic Fields Produced by Currents Electric Current Creates Magnetic Right-Hand Rule Fields The direction of the magnetic field can be predicted using the Moving charges, like those in a current-carrying wire, right-hand rule, where the thumb points in the direction of generate a magnetic field around them. current, and the curled fingers represent the magnetic field lines. preencoded.png Magnetic Fields Produced by Currents it is expected that a magnetic field at a given point would be greater if the current flowing in the wire is greater; and the magnetic field would be lesser at points farther from the wire. preencoded.png Force Between Parallel Wires Attractive Force When currents flow in the same direction, the magnetic fields created by each wire interact, resulting in an attractive force between them. Repulsive Force Conversely, if currents flow in opposite directions, the magnetic fields repel each other, causing a repulsive force. preencoded.png Force Between Parallel Wires A long straight current carrying wire when placed in n logically speaking, it follows that when two straight current external magnetic field will experience a magnetic force. in carrying wires are placed near each other, each would create the same manner, that a current could be a source of a magnetic field that in turn causes a magnetic force on each magnetic field as proven by the deflection of the compass other. when brought near a current. preencoded.png Ampere's Law Relationship Ampere's law describes the relationship between magnetic fields and the electric 1 currents that produce them. Line Integral 2 It states that the line integral of the magnetic field around a closed loop is proportional to the total current enclosed by the loop. Applications Ampere's law is fundamental to understanding and calculating 3 magnetic fields in various scenarios, including solenoids and electromagnets. preencoded.png Solenoids: Creating Strong Magnetic Fields Strong, Uniform Electromagnets Field Solenoids are commonly used A solenoid is a coil of wire to create electromagnets, wound into a tight helix. When where the magnetic field can current flows through it, it be controlled by adjusting the creates a strong and uniform current flowing through the magnetic field inside the coil. coil. Applications Solenoids have numerous applications, including in electric motors, magnetic levitation, and medical imaging. preencoded.png
