Hi, I looked it up, and I tried to use the right hand rule, but I don´t understand how to do it when I don´t know the direction of the power. I tried with the power having the direction "into the paper", and used the right hand rule, and then it worked, but I don´t know why. Can you please explain?Doc Al said:
What do you mean by "power"? You are given the directions of the charge's velocity and the magnetic field. That should be all you need to find the direction of the magnetic force on the charge.agnwib said:
By "power" I meant the electric current. Normally, when I use the right hand rule I keep my thumb and index finger still, and bend the other fingers (middle finger, ring finger and pinky). Then I place the index finger in the direction of the electric current, the three bend fingers in the direction of the magnetic field and my thumb shows the direction of the magnetic force. I don´t know how to use this rule at this task because I don´t know the direction of the electrical currentDoc Al said:
In this problem there is only a single charge moving. That moving charge is the current.agnwib said:
Okey, I understand. Does that mean that that when I use the right hand rule, the index finger should point to north (because the positive charged particle has valocity to that direction)? Because when I do this, I still get wrong answer.Doc Al said:
Yes, using your version of the right hand rule (which is OK).agnwib said:
So, you have your index finger pointing north and your other fingers pointing west?agnwib said:
There are many versions of the right hand rule. The one used by the OP is fine. (As is yours.)salmanshu322 said:
A magnetic field can exert a force on a charged particle, causing it to experience a change in direction or velocity. This is known as the Lorentz force and is dependent on the charge of the particle, its velocity, and the strength and direction of the magnetic field.
No, a magnetic field can only alter the path of a charged particle. The particle's initial velocity and the strength of the magnetic field will determine the extent of the deflection.
A uniform magnetic field has the same strength and direction throughout, while a non-uniform magnetic field varies in strength and/or direction. In a uniform magnetic field, a charged particle will experience a constant force and move in a circular path, while in a non-uniform magnetic field, the particle's path may be more complex.
The mass of a charged particle does not directly affect its motion in a magnetic field. However, a particle with a larger mass will require a stronger magnetic field to produce the same amount of deflection as a particle with a smaller mass.
Yes, a magnetic field can affect the speed of a charged particle by changing its direction of motion. The speed of the particle will remain constant, but its velocity will be altered due to the magnetic force acting on it.
