So draw the arrows to find how you have to add them.Fatima Hasan said:Yeah
B2 = 8μT (-j) , because the direction of I2 is (-i).BvU said:So draw the arrows to find how you have to add them.
I'd vote for ##-\hat k##Fatima Hasan said:the direction of I2 is (-i)
So , B2 (##-\hat j##)BvU said:I'd vote for ##-\hat k##
The magnetic field at a point is a vector quantity that describes the strength and direction of the magnetic force experienced by a charged particle at that point. It is measured in units of tesla (T) in the SI system.
The magnetic field at a point can be calculated using the formula B = μ0 * (I / 2πr), where B is the magnetic field, μ0 is the permeability of free space (4π * 10^-7 T*m/A), I is the current, and r is the distance from the point to the current-carrying wire. This formula is known as the Biot-Savart Law.
Several factors can affect the magnetic field at a point, including the strength of the current, the distance from the current-carrying wire, and the orientation of the wire relative to the point. The material surrounding the wire can also have an impact on the magnetic field.
The direction of the magnetic field at a point is determined by the right-hand rule. If you point your right thumb in the direction of the current, the direction of your curled fingers will indicate the direction of the magnetic field.
Yes, the magnetic field at a point can be shielded or blocked by certain materials. For example, materials with high magnetic permeability, such as iron or steel, can redirect the magnetic field lines away from the point. Additionally, the use of a Faraday cage can effectively block the magnetic field at a point from outside interference.
