The Physics Classroom explains the meaning of force
Name: _____ The Force Be with You! by Cindy Sherwood 1. Where does the force that creates a magnetic field come from? a. the activity of protons in atoms... The magnetic field at a point is in the direction of the force a north pole of a magnet would experience if it were placed there. In other words, the north pole of a compass points in the direction of the magnetic …

Try to come up with at least two methods to move the magnet on the sheet of the paper using the other mag- net. Explain the two methods your group came up with.... The magnetic lines of force, or flux, leave the north pole and enter the south pole. How is the earth like a magnet? Since the earth is a huge magnet with a magnetic north and south pole, the lines of magnetic force around the earth look like there is a huge vertical bar …
What are magnetic fields? (article) Khan Academy
19/04/2015 · Putting a magnet on your fridge magnetizes the iron in the fridge door (or, rather, it organizes the already magnetic domains in the iron), and then the door can pull back on the fridge magnet in the usual north-to-south way. flatten a pdf in preview The magnetic field of the Earth is fairly weak on the surface. After all, the planet Earth is almost 8,000 miles in diameter, so the magnetic field has to travel a long way to affect your compass.

The magnetic force on a current-carrying conductor underpins every electric motor - turning the hands of electric watches and clocks, transporting tape in Walkmans, starting cars, operating refrigerator compressors, etc. amy bloom come to me pdf The direction of the magnetic force on a moving charge is perpendicular to the plane formed by v and B and follows right hand rule–1 (RHR-1) as shown. The magnitude of the force is proportional to q, v, B, and the sine of the angle between v and B.

Where Does Magnetic Force Come From Pdf
A magnetic field is a picture that we use as a tool to describe how the magnetic force is distributed in the space around and within something magnetic. [Explain] When we speak of the force due to a magnet (or any force for that matter) it has to be on something.
- Magnetic-field lines pass through cardboard, air, and certain other materials, depending on whether they're permeable or nonpermeable. Test different materials to see which gather magnetic lines of force and act as magnetic shields, and which allow magnetic lines of force to pass through them.
- CLASS-10TH -CHAPTER -13 MAGNETIC EFFECTS OF ELECTRIC CURRENT [Type text] Page 3 Figure 13.10 (Page No.229 NCERT Text Book) Answer: Pattern of magnetic field lines It indicates that the magnetic field is the same at all
- What effect does the magnetic field have on the speed of the particle? ANSWER: 4.9 A 7.6 A 2.5 A 9.8 A 1.2 A )F g Ã Since both the electric force and magnetic force depend on , in particular, they also depend on its sign. So the sign doesn't matter here. Apply the righthand rule to the equation for the magnetic force, . Hint 2. Righthand rule Curl the fingers of your right hand from
- 2 Magnetism The earth is a gigantic magnet, with a North Pole and South Pole. As a permanent magnet it is surrounded by a magnetic field. Since the North Pole of a magnet refers to the North, and
