Explanation Formula to calculate net magnetic field at point 1 is, B net 1 = B 1 + B 2 (1) Here, B 1 is the magnetic field at point 1 due to vertical wire. B 2 is the magnetic field at point 1 due to horizontal wire. Write the expression for magnetic field at any point 1 due to vertical wire. B 1 = μ o I 2 π r ( into the page ) = − μ o I 2 π r Here, μ o is the magnetic permeability in free space. I is the current flowing through the wire. r is the distance of point 1 from the vertical wire. Write the expression for the magnetic field at point 1 due to horizontal wire. B 2 = μ o I 2 π r ( out of page ) = μ o I 2 π r Substitute μ o I 2 π r for B 1 and − μ o I 2 π r for B 2 in equation (1). B net 1 = μ o I 2 π r + ( − μ o I 2 π r ) = 0 Formula to calculate net magnetic field at point 2 is, B net 2 = B 1 + B 2 (2) Here, B 1 is the magnetic field at point 2 due to vertical wire. B 2 is the magnetic field at point 2 due to horizontal wire. Write the expression for magnetic field at any point 2 due to vertical wire. B 1 = μ o I 2 π r ( out of page ) = μ o I 2 π r Here, I is the current flowing through the wire. r is the distance of point 1 from the vertical wire. Write the expression for the magnetic field at point 2 due to horizontal wire. B 2 = μ o I 2 π r ( out of page ) = μ o I 2 π r Substitute μ o I 2 π r for B 1 and μ o I 2 π r for B 2 in equation (2). B net 2 = μ o I 2 π r + ( μ o I 2 π r ) = μ o I π r Formula to calculate net magnetic field at point 3 is, B net 3 = B 1 + B 2 (3) Here, B 1 is the magnetic field at point 3 due to vertical wire

Magnetic Force

A magnetic force arises when a charged particle or a current-carrying conductor is placed in a magnetic field. It is created because of the movement of the charged particles.

You are working with a movie director and investigating a scene with a cowboy sliding off a tree limb and falling onto the saddle of a moving horse. The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.55 m off the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.660 m before his body comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to calculate the average force upward on his body from the ground, as a multiple of the cowboy's…

A box of mass m = 2.00 kg is released from rest at the top of an inclined plane as seen in the figure. The box starts out at height h =0.200 m above the top of the table, the table height is H = 2.00 m, and 0 = 41.0°. H m (a) What is the acceleration (in m/s²) of the box while it slides down the incline? m/s² (b) What is the speed (in m/s) of the box when it leaves the incline? m/s (c) At what horizontal distance (in m) from the end of the table will the box hit the ground? m (d) How long (in s) from when the box is released does it hit the ground? S (e) Does the box's mass affect any of your above answers? Yes No
