Answer 2

Correct Statements:

A. A magnetic field can be detected by its effect on stationary charged particles. The presence of a magnetic field can be observed by its influence on stationary charged particles, such as the deflection of a compass needle or the movement of iron filings in the field [[1]].

C. An electric current creates a magnetic field. According to Ampere's law, a current-carrying wire produces a magnetic field around it. The magnetic field strength is directly proportional to the current flowing through the wire [[2]].

E. An external magnetic field acts on a conductor with a current. When a conductor carrying an electric current is placed in an external magnetic field, a force is exerted on the conductor due to the interaction between the magnetic field and the current. This phenomenon is known as the magnetic force on a current-carrying conductor [[3]].

G. A magnet can be detected by its effect on iron objects. A magnet can be identified by its ability to attract or repel iron objects. When a magnet is brought close to iron objects, they experience a force of attraction or repulsion, indicating the presence of a magnetic field [[4]].

H. A magnet exerts a certain force on a wire carrying current. When a wire carrying an electric current is placed in a magnetic field, a force is exerted on the wire due to the interaction between the magnetic field and the current. This force can be observed by the deflection or movement of the wire [[5]].

J. Magnetic interaction is transmitted through the magnetic field. The interaction between magnetic objects or currents is transmitted through the magnetic field. Changes in the magnetic field can affect the behavior of magnetic objects or currents in their vicinity [[6]].

K. A magnetic field can be detected by its effect on current-carrying conductors. When a current-carrying conductor is placed in a magnetic field, it experiences a force due to the interaction between the magnetic field and the current. This force can be observed by the deflection or movement of the conductor [[7]].

L. A magnetic field can be detected by its effect on magnets. A magnetic field can be identified by its influence on magnets. When a magnet is brought close to another magnet, they can attract or repel each other, indicating the presence of a magnetic field [[8]].

Incorrect Statements:

B. The correct statement should be: A magnetic field acts on moving charged particles. A magnetic field exerts a force on moving charged particles, not stationary ones. The force experienced by a charged particle depends on its velocity and the strength of the magnetic field [[9]].

D. The correct statement should be: Electric and magnetic phenomena are related to each other. Electric and magnetic phenomena are closely related and are described by Maxwell's equations. Changes in electric fields can induce magnetic fields, and changes in magnetic fields can induce electric fields. This relationship is known as electromagnetic induction [[10]].

I. The correct statement should be: Magnetic interaction is transmitted through the magnetic field. The interaction between magnetic objects or currents is transmitted through the magnetic field, not through the electric field.
