If the current is alternating, the magnetic field will also be alternating.
would induce a current in the coil itself, creating a self-induced electromagnetic field. This field would interact with the original field, leading to a stronger magnetic effect and potentially affecting nearby conductors or devices. The coil's shape and number of turns would also impact the strength and direction of the induced field.
When a magnetic field is parallel to a current-carrying wire, there is no force acting on the wire. This is because the magnetic force on a current-carrying wire is perpendicular to both the current and the magnetic field.
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
Fleming's right hand rule shows the direction of induced current flow when a conductor moves in a magnetic field. Fleming's left hand rule shows the direction of the thrust on a conductor carrying a current in a magnetic field.
A changing magnetic field A conductor or coil of wire Movement between the magnetic field and the conductor (relative motion)
To increase the magnetic force in a current-carrying coil or conductor, you can increase the current flowing through it, increase the number of loops in the coil, or use a material with higher magnetic permeability around the coil. These methods will strengthen the magnetic field generated by the coil or conductor.
The magnetic field produced around a current carrying conductor can be detected using a magnetic compass, a Hall effect sensor, or a magnetometer. These devices can detect the direction and strength of the magnetic field generated by the current flowing through the conductor.
Hall Effect
A wire cannot cause a magnetic field if there is no current flowing through it. Magnetic fields are generated by the flow of electric current in a conductor.
A magnetic field is generated around a magnet or a current-carrying conductor. It exists in the space surrounding the magnet or conductor, affecting other magnets or conductors within its influence. Magnetic fields are also present in certain materials and celestial bodies.
The force experienced by a current-carrying conductor in a magnetic field is strongest when the current and magnetic field are perpendicular to each other, maximizing the force according to the right-hand rule.
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
a magnetic field
When a current-carrying conductor is placed in a magnetic field, a force is exerted on the conductor due to the interaction between the magnetic field and the current. This force is known as the magnetic Lorentz force and its direction is perpendicular to both the magnetic field and the current flow. The magnitude of the force depends on the strength of the magnetic field, the current flowing through the conductor, and the length of the conductor exposed to the magnetic field.
When the conductor,magnetic field and motion are perpendicular to each other
because transformer in made inductorAlternative AnswerTransformers are AC machines, and do not work with DC. This is because they require an alternating current to set up an alternating magnetic flux which then induces an alternating voltage into its secondary. Remember, there has to be a changing magnetic flux and a conductor for an emf. to be induced into that conductor.
The shape of the magnetic field lines around a straight current-carrying conductor is circular, with the conductor at the center of each circular loop. These magnetic field lines form concentric circles around the conductor, perpendicular to the direction of the current flow.
