The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.

As it is covered by Biot– Savart law, the magnetic field strength is inversely proportional to the distance from the current carrying conductor. In this application- note we will be using the same concept in the position-sensing application.

There are actually two general types of electromagnetic forces: electrostatic forces and magnetic forces.

Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. Practically this means the following: If the current is doubled the force on the conductor will double.

['Apply the equation. to find the magnitude, which is 1.4.', 'Apply the equation theta = tan–1(y/x) to find the angle: tan–1(1.0/–1.0) = –45 degrees. However, note that the angle must really be between 90 degrees and 180 degrees because the first vector component is negative and the second is positive.']

Right hand rule: When determining the direction of an angular vector, use the right hand rule: curl the fingers of your right hand in the direction of the circular motion and your thumb points in the vector direction. The units of angular velocity are radians per second.

Think of the x coordinate of the force as the base of a triangle, the y component as the height of the triangle, and the hypotenuse as the resultant force from both components. Extending the link, the angle the hypotenuse makes with the base is the direction of the force. So, 5 N is the magnitude of force.

The magnetic moment is the magnetic strength and orientation of a magnet or other object that produces a magnetic field. ... The direction of the magnetic moment points from the south to north pole of the magnet (inside the magnet). The magnetic field of a magnetic dipole is proportional to its magnetic dipole moment.

Magnetic lines of force have a number of important properties, which include: They seek the path of least resistance between opposite magnetic poles. In a single bar magnet as shown to the right, they attempt to form closed loops from pole to pole. They never cross one another.

= 1.5 × 10−3 kg The mass of the object is 1.5 × 10−3 kg = 1.5 g. That's the magnitude of the electron's acceleration. Since the electron has a negative charge the direction of the force on the electron (and also the acceleration) is opposite the direction of the electric field.

RHR-1 states that, to determine the direction of the magnetic force on a positive moving charge, you point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.

The acceleration is in the same direction as the net force. to find the magnitude of the net force, giving you 102 N. Use the magnitude of the force and the mass to find the magnitude of the acceleration: a = F/m = (102 N)/(100 kg) = 1.0 m/s2.
