Right-Hand Rule #1 determines the directions of magnetic force, conventional current and the magnetic field. Given any two of theses, the third can be found. point your index finger in the direction of the charge's velocity, v, (recall conventional current). Your thumb now points in the direction of the magnetic force, F magnetic.

In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.

In what direction is the force on a positive charge with a velocity to the left in a uniform magnetic field directed down and to the left? In what direction is the force on a negative charge with a velocity down in a uniform magnetic field directed out of the screen?

2018年4月13日 · 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. Calling these "rules" is the right name.

2024年11月24日 · The direction of curl of the magnetic field can be found using a modified right hand rule: The thumb points in the direction of conventional current. The curl of the fingers indicates the direction of magnetic field at each location surrounding the flow of current.

Right Hand Rules in Magnetism #1 Cross Product RHR 1.Put your arm in the direction of the first vector. 2.Bend your fingers to point in the direction of the second vector. 3.Your thumb points in the direction of the cross product. This applies to: • Magnetic force on a moving charge: F⃗ q = q⃗v×B⃗ • Magnetic force on a current: F⃗

2023年2月15日 · To use the right-hand (RHR) rule, as the name implies use your right hand, point your thumb in the direction of the charge's velocity, your index finger in the direction of the component of the magnetic field which is perpendicular to the velocity, and your middle figure which is perpendicular to the other two will tell you the direction of the ...

What direction is the force on a positive charge when entering a uniform B field in the direction indicated? conducting slab has current to the right. A B field is applied out of the page. Due to magnetic forces on the charge carriers, the bottom of the slab is at a higher electric potential than the top of the slab.

Magnetic Field At Center of a Current Loop This is basically an extension of the previous example, but if you have current owing around a loop in some direction, this right-hand rule provides the direction of the magnetic eld within the loop. The middle gure is a reminder that magnetic eld lines are themselves closed loops: they
