Final answer:
A current-carrying wire can be accelerated by a magnetic field due to the interaction between the magnetic field and the moving charges in the wire. This phenomenon is explained by Faraday's law of induction, which states that a changing magnetic flux through a loop induces an electromotive force (emf) in the circuit. The emf can result in the acceleration of the wire in the presence of a magnetic field.
Step-by-step explanation:
A current-carrying wire can be accelerated by a magnetic field. This is possible due to the interaction between the magnetic field and the moving charges in the wire. When a current flows through the wire, it creates a magnetic field around it. The magnetic field exerts a force on the wire, causing it to experience both forces and torques.
This phenomenon can be explained using Faraday's law of induction. When the current in the wire changes, the magnetic flux through the loop also changes. This change in flux induces an electromotive force (emf) in the circuit. The induced emf can lead to the acceleration of the wire in the presence of a magnetic field.
For example, when a current-carrying wire is placed in a uniform magnetic field, the wire experiences a force. This force is given by the equation F = I x B, where I is the current and B is the magnetic field. The direction of the force can be determined using the right-hand rule.
