Why hall voltage increases with increase in magnetic field?
Since eEH= e(V X B) As magnetic field increases the lorentz force acting on the carriers increases which in turn increases the hall field associated with the carriers and hence hall voltage increases as magnetic field is increased.
How can you increase the volume of a balloon without increasing the temperature?
Decrease the pressure of the surrounding environment. Thus, the force acting on the balloon from the outside decreases, allowing the air pressure that creates a force inside the balloon to have less of a counteracting force.
Which increase the amount of carbon dioxide in the atmosphere acting as a carbon source?
Respiration :)
What will be the effect if a wheel magnet received from a speaker is binded by insulated copper wire and used in place of simple inductance coil?
So already magnetic field is there in the coil but there is no change of flux inside the coil. So its basically acting as a normal metal core. But on inducing emf the direction of the current flowing in the circuit will determine the field developed by the coil but it will be either diminished or amplified depending on the direction of the induced magnetic field because of the permanent magnet.
Which property of a magnet is the reason why a magnet is used in a compass?
Its magnetism and the fact that the magnetism is the biggest force acting on the needle on the XY plane. This force is bigger than the friction from the spindle and the force of inertia. (The force of gravity is bigger but this acts on the Z plane) As the magnetism is the biggest force acting on the alignment of the needle it means it wants to align itself with the earths magnetic field. The result is a needle that points to magnetic north
What is the purpose of Fleming's right hand rule?
Fleming's right hand rule is used to determine the direction of the magnetic force on a current-carrying conductor in a magnetic field. By aligning the thumb with the direction of current flow, the forefinger with the direction of the magnetic field, the middle finger points in the direction of the magnetic force acting on the conductor.
What did Andre ampere discovered?
Ampere disconvered the relationship between the magnitude of an electric current and the force acting on a current-carrying conductor within a magnetic field. Thus, the unit of current, the ampere, was named in his honour.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
How can the pressure acting on the surface be increased by the force acting on the surface?
Simply pressure is the force per unit area. So Pressure is directly proportional to the force applied. Hence by increasing the force we can increase the pressure.
Why hall voltage increases with increase in magnetic field?
Since eEH= e(V X B) As magnetic field increases the lorentz force acting on the carriers increases which in turn increases the hall field associated with the carriers and hence hall voltage increases as magnetic field is increased.
what rule is applied in case of dc motor?
You may be thinking of Fleming's Left-Hand Rule (for conventional current flow) or Fleming's Right-Hand Rule (for electron flow), devised by academic Sir Ambrose Fleming, as a aid for determining the direction of the resulting force acting on a current-carrying conductor within a magnetic field, when the direction of current and the direction of the magnetic field are known.
Why a three phase induction motor is self stating?
when you excite the 3-phase coils with an alternating supply,It produces a rotating magnetic field which interacts with the windings/conductor on the rotor & produces a current. According to Lenz's law the current induced is opposite in nature to the cause producing it & hence the magnetic field produced by this current will be opposite in nature to the rotating magnetic field in the stator.Hence due to interaction of these two forces a torque will be acting on the rotor which will make the rotor to rotate. Hence it is self-starting .
How does mass affect the force acting on a object?
The equation that illustrates Newton's 2nd Law is F=ma, or a=F/m. If you wish to keep the acceleration constant, increasing the mass requires an increase in force.
Suppose that you're facing a straight current-carrying conductor and the current is flowing toward you the lines of magnetic force at any point in the magnetic field will act in?
The lines of magnetic force at any point in the magnetic field of a current flowing towards you will act in the counter clockwise direction. This can be determined by using the right hand rule. Point your thumb in the direction of the current flowing down the straight wire. The curl of your fingers shows the direction of the magnetic lines of flux. The magnetic field of a current is always perpendicular to it. A current facing away from you would produce magnetic lines of force acting in the clockwise direction.
What is a magnetic field vector?
It is a way of representing the magnetic force at a point in the field. The magnitude and direction of the vector represents the strength and the direction of the magnetic force acting on a charged particle in the field.
What is the force of repulsion acting on each sphere?
What force is acting? Gravity? Electricity? Magnetic repulsion? And what is the mass/charge on each sphere anyway?
Why magnetic force is a force acting on a distance?
because it have a molten liquid contain iron
