Direction of Force (Right Hand Rule) The direction of the force on a particle from the magnetic field is not as straight forward as the force and electric field. You have to use the Right Hand Rule (RHR) to determine the direction because it is not the same as the direction of the magnetic| field. In the image below a charged particle is moving. The direction of motion is shown with the arrow labeled v (velocity). The magnetic field is also shown with additional arrows (labeled B). B (Magnetic Field) v (velocity – into the page) Proton + What is the direction of the Force on this particle in this Magnetic Field? Make sure to consider the particle (electron or proton) as that will have an effect on the answer. Note: For those of you in or who have taken higher levels of calculus, this direction is also the result of doing a cross product matrix. You can figure out the answer this way without dislocating your wrist :) + x (to the right) - y (downward) -x (to the left) - z (into the…

Estimates: since the force it takes to separate one magnet from your refrigerator is nearly the same as the force it takes to separate two magnets stuck together, that force F is 5 N and the area of a refrigerator magnet is 8 cm?. Assume that when these magnets are stuck together or to the refrigerator, they are separated by an effective distance d = 25 um. Use the formula derived above to estimate the magnetic field strength of the magnet. Express your answer to one significant figures and include the appropriate units.

Right hand rule for magnetic field due to a long straight current: Magnetic field lines are a way to graphically represent I the magnetic field. The direction of B at any point is tangent to the field line and the magnitude of B is proportional to the density of field lines. For the long straight wire, the magnetic I field lines form circles around the wire. There is a right hand rule for the direction in the magnetic field go around the wire. Grasp the wire with your thumb in the direction of the current. The direction your fingers wrap around the wire is the direction that the B field lines go around the wire. Check that this agrees with your analysis of the long straight wire from the previous problem. lines В Magnitude of magnetic field due to a long straight current: The magnitude of the magnetic field at a distance r due to a very long straight wire carrying current I can be derived from dB O the Biot-Savart law: HoI ds sin ø HOID ds dB 4π (s2+ D?) 4π(s2+ D2)3/2 D where we used…

You have learned that a charge moving in an magnetic field can experience a magnetic force.  Remarkably, anytime that a charged particle moves that particle produces its own magnetic field! The image below of magnetic compasses forming a circle around a current-carrying wire demonstrates the shape of the magnetic field.  The magnetic field lines forms concentric circles around that wire. The strength of the field decreases with increasing distance away from the wire. If the current in the wire is 1.15A, what is the magnitude of the magnitude of the magnetic field (in ?μT, or micro-Tesla) a distance of 0.88m away from the wire?

Which of the following are true, regarding magnetic fields and forces?Select all that are True. The maximum magnetic force on a charged particle occurs when the particle's velocity is parallel to the magnetic field. Earth's north magnetic pole is currently near the planet's south geographic pole. Magnetic forces can perform work on charged particles. If a positively-charged particle is moving in counterclockwise circles in the plane of the screen, the magnetic field must be pointing into the screen. Magnetic field lines exit the south pole of a bar magnet and enter its north pole. If a charged particle is moving in circles in a magnetic field, and the radius of its circular path is decreasing, its speed must be increasing.
