i have questions for lorentz force simulation in 3d
i did following steps for determine value of lorentz force of a wire :
1.after selection magnetic field physic, i define a box as wire and sphere as air in geometry
2.define materials air and aluminum
In physic
3. i define background magnetic field 0.5 T in x direction
4. i define a external current density 1.11111e9 A/m^2 in y direction in wire
(depending on right hand low abut lorentz force)
5. i define force calculation for wire
compute
now from result tree in derived value , global evalution i get from mechanical , magnetic force the value of it
1. why changing in size of sphere make change in lorentz force of wire , which is true?
2. why i cant simulate lorentz force of wire without air define , and it give 0 N value of magnetic force ?
3. if i want couple result of this physic that is force to solid mechanic physic for defining that force for body load force , after defining fix constraint domain , what i should do ?
4. why after defination solid mechanic physic we need poisson ratio and young modulus for air ? that a red sign tell we dont define them for air , what i should do ?
5. did i do steps true ?
thank you
