what is the right hand rule for vectors?
The length of the vector gives the speed of rotation and the direction of the axis gives the direction of rotation according to the right–hand rule: right fingers curled in the direction of rotation and the right thumb pointing in the positive direction of the axis.
what is the right hand rule geology?
Geologists use strike, which is an imaginary horizontal line on a plane measured from the North. It is usually given in degrees. According to the Right Hand Rule (RHR), the strike direction depends on the dip. Based on the dip direction, one can obtain the direction of the strike.
what is the meaning of right hand rule?
right–hand rule. A rule that uses the shape the right hand to established the standard orientation of vector quantities normal to a plane, especially when calculating a vector product or the helicity of particle spin.
Where is Fleming’s left hand rule used?
The middle finger points in the direction of the current. The thumb gives the direction of force or motion acting on the conductor. Fleming’s Left Hand Rule is used in electric motors which are used in fans, mixers, printers, etc.
What is the right hand screw rule?
The right hand screw rule can be used when a direction must be determined based upon a rotational direction, or vice versa. The axis is ‘grasped’ in the right hand, the fingers curl round in the direction of positive rotation and the thumb is orientated in the positive direction.
What is the second right hand rule?
The second right hand rule deals with the magnetic field that is induced by current moving through a wire. (a wire coiled around a core) Wrap your fingers around the solenoid in the direction of current flow through the wire. Your thumb represents the “North” direction of the induced magnetic field!
What do you mean by flux?
The noun flux describes something that constantly changes. If your likes, dislikes, attitudes, dreams, and even friends are changing all the time, you may be in flux. Flux can also mean being unsure about a decision. Another kind of flux is liquid moving or flowing, like the flux of water under a sheet of melting ice.
What is the difference between left and right hand rule?
Fleming’s left-hand rule is used for electric motors, while Fleming’s right-hand rule is used for electric generators. Since neither the direction of motion nor the direction of the magnetic field (inside the motor/generator) has changed, the direction of the electric current in the motor/generator has reversed.
What is right hand rule and left hand rule?
Fleming’s left-hand rule is used for electric motors, while Fleming’s right-hand rule is used for electric generators. In an electric motor, the electric current and magnetic field exist (which are the causes), and they lead to the force that creates the motion (which is the effect), and so the left hand rule is used.
How many right hand rules are there?
Some would claim that there is only one right-hand rule, but I have found the convention of three separate rules for the most common situations to be very convenient. These are for (1) long, straight wires, (2) free moving charges in magnetic fields, and (3) the solenoid rule – which are loops of current.
What is a good rule of thumb?
rule of thumb. phrase. A rule of thumb is a rule or principle that you follow which is not based on exact calculations, but rather on experience. A good rule of thumb is that a broker must generate sales of ten times his salary if his employer is to make a profit.
What is Dot and cross product?
Dot product, the interactions between similar dimensions ( x*x , y*y , z*z ) Cross product, the interactions between different dimensions ( x*y , y*z , z*x , etc.)
