What is the principle of motor action?
Motor runs by the principle of Michael Faraday's Electromagnetic Induction. It is defined as "when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field". The direction of rotation is determined by the Right-hand Rule and is "if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand".
What is thumb rule related to magnetic field and current?
THUMB RULE:If we put our one thumb in the direction of magnetic flux passes through the conductor,then the movement of the fingures denotes the direction of current flow.
What is flaming left hand rule?
Stretch the thumb the first finger and the central finger of the left hand so that they are mutually perpendicular to each other. If the first four finger points in the direction of magnetic field the central finger points in the direction of current then the thumb points in the direction of motion of the conductor is known as fleming's left hand rule. by Prosenjit.
Why electromagnetic torque opposes prime mover torque in dc generator?
It's a practical example of the conservation of energy, and is explained by Lenz's Law. The direction of the load current is such that its magnetic field will create a force acting in the opposite direction to the force causing the conductor to move in the first place.
What are the factors that determine the size and direction of the emf generated by the permanent magnet generator.?
number of conductors speed magnitude of the magnetic flux
To use your left hand to derermine the direction of the voltage developed in a moving conductor in a stationary magnetic field ou must point your?
The answer choices weren't provided. To use your left hand to determine the direction of the voltage developed in a moving conductor in a stationary magnetic field you must point your forefinger in the direction of the lines of force.
To use your left hand to determine the direction of the voltage developed in?
To use your left hand to determine the direction of the voltage developed in moving conductor place your forefinger in the direction of the lines of force. Fleming developed this hand rule.
To use your left hand to determine the direction of the voltage developed in moving conductor in a stationary magnetic field you must point your?
forefinger in the direction of the lines of force
How does the right hand rule work to determine the direction of a magnetic field around a current-carrying conductor?
The right-hand rule is a way to determine the direction of a magnetic field around a current-carrying conductor. Point your thumb in the direction of the current flow, and curl your fingers. The direction your fingers curl represents the direction of the magnetic field around the conductor.
What is the right hand rule and how is it used to determine the direction of a magnetic field around a current-carrying conductor?
The right-hand rule is a method used to determine the direction of a magnetic field around a current-carrying conductor. To use the rule, point your thumb in the direction of the current flow and curl your fingers. The direction your fingers curl represents the direction of the magnetic field around the conductor.
What is the right hand curl rule and how is it used to determine the direction of the magnetic field around a current-carrying conductor?
The right-hand curl rule is a method used to determine the direction of the magnetic field around a current-carrying conductor. To apply the rule, point your right thumb in the direction of the current flow. Then, curl your fingers around the conductor. The direction your fingers curl represents the direction of the magnetic field lines around the conductor.
Is the right hand rule for protons or electrons used to determine the direction of the magnetic field created by a current-carrying conductor?
The right-hand rule is used to determine the direction of the magnetic field created by a current-carrying conductor.
What is the right hand rule in physics and how is it used to determine the direction of a magnetic field around a current-carrying conductor?
The right-hand rule in physics is a method used to determine the direction of a magnetic field around a current-carrying conductor. To apply the rule, point your right thumb in the direction of the current flow and curl your fingers. The direction in which your fingers curl represents the direction of the magnetic field around the conductor.
What is the right hand rule in physics and how is it used to determine the direction of a magnetic field in relation to the current flow in a conductor?
The right-hand rule in physics is a method used to determine the direction of a magnetic field in relation to the current flow in a conductor. To use the right-hand rule, point your thumb in the direction of the current flow and curl your fingers. The direction your fingers curl represents the direction of the magnetic field around the conductor.
What is the left hand rule of electromagnetism and how is it used to determine the direction of the magnetic field created by a current-carrying conductor?
The left-hand rule of electromagnetism is a rule used to determine the direction of the magnetic field created by a current-carrying conductor. To use this rule, point your thumb in the direction of the current flow, your index finger in the direction of the magnetic field, and your middle finger will then point in the direction of the force acting on the conductor. This rule helps in understanding the relationship between current flow and magnetic fields.
What is the purpose of the right hand rule diagram in understanding the direction of magnetic fields around a current-carrying conductor?
The purpose of the right hand rule diagram is to help visualize the direction of magnetic fields around a current-carrying conductor. By using your right hand and following the rule, you can determine the direction of the magnetic field based on the direction of the current flow in the conductor.
How rigt hand thumb rule is used in determining the direction of magnetic field around a conductor carrying current?
Curl the fingers of your right hand into the palm and extend the thumb. The thumb indicates the direction of the current, and the direction of the fingers indicates the direction of the magnetic field.
