This equation gives the force on a straight current-carrying wire of length ℓ in a magnetic field of strength B. The angle θ is the angle between the current vector and the magnetic field vector. Note that ℓ is the length of wire that is in the magnetic field and for which θ ≠ 0, as shown in Figure 20.19.

WebThe field-line description has some useful properties: Magnetic field lines never cross. Magnetic field lines naturally bunch together in regions where the magnetic field is the strongest. This means that the density of field lines indicates the strength of the field. WebWhile the general pattern will always be the same, the exact position and density of lines of filings depends on how the filings happened to fall, their size and magnetic properties. … WebOct 12, 2014 · Each substance retains its original properties, and can be separated by physical means. Challenge your student to design a method to separate a mixture into its separate components. First, you’ll need to make the mixture that will be separated.
