Both the electric field and magnetic field can be defined from the Lorentz force law: The electric force is straightforward, being in the direction of the electric field if the charge q is positive, but the direction of the magnetic part of the force is given by the right hand rule.
In mathematics and physics, the right-hand rule is a common mnemonic for understanding orientation conventions for vectors in three dimensions. Most of the various left- and right-hand rules arise from the fact that the three axes of 3-dimensional space have two possible orientations.
Right-Hand Rules: A Guide to finding the Direction of the Magnetic Force. Fmagnetic - The force a magnetic field exerts on a moving charge.
• Magnetic fields are similar to electric fields, but they are produced only by moving charges while electric fields are produced by both moving charges and stationary charges.
Rule 3 relates the directions, at any instant at any point in space, for the magnetic and electric fields associated with an electromagnetic wave. t- is the velocity of propagation of the wave.
The Right Hand Rule for Electric Current through a Wire (or Solenoid). Movement of any charged particles creates a magnetic field (B). For electricity, the charged particles are electrons, which are negatively charged.
The cause of the Earth's magnetic field is not well understood, but it is assumed that it is due to electric currents circulating inside the Earth.
Principle of Electromagnetism: Moving electric charges produce a magnetic field. Right hand Rule for a Straight conductor: If a conductor is grasped in the right hand, with the thump pointing in the direction of the current, the curled fingers point in the direction of the magnetic field lines.
Right-hand rule. The left-handed orientation is shown on the left, and the right-handed on the right.
Electromagnetic Induction Too Fleming’s Right Hand Rule. Michael Faraday found that moving a conductor in a magnetic field (or by moving the magnet field near a stationary conductor)
