yes the current through the wire is 5 A and 30 grades=pi/6 radiandrvrm said:i think by intensity 5A you mean the current through the wire.
the other angle given "when it forms with the force the angle 30 grades" what grades signifies- see conversion of grades to degree.

I translated it. but the angle is pi/6 radiandrvrm said:So , one grade =pi/180 radians, then why one uses a different names-give reference
If you understood the problem, could you tell me if I have done it correctly because my solution is different from the one in the bookdrvrm said:So , one grade =pi/180 radians, then why one uses a different names-give reference

We use this kind of relationship in physics everyday. I'm sure that the angle is pi/6 radiandrvrm said:well i looked for the unit grade as angle measurer
The gradian is a unit of measurement of an angle, equivalent to 1⁄400 of aturn,[1] 9⁄10 of a degree or π⁄200 of a radian.
It is also known as gon (from Greek γωνία/gōnía for angle), grad, or grade. In continental Europe,

so if you use the conversion does the result change?

The formula for calculating the force exerted by a magnetic field on a wire is F = BIL, where F is the force in Newtons, B is the magnetic field strength in Teslas, I is the current in amperes, and L is the length of the wire in meters.
The force on the wire is perpendicular to both the direction of the magnetic field and the direction of the current. This is known as the right-hand rule. If you point your right thumb in the direction of the current, your fingers will curl in the direction of the magnetic field, and the force will be in the direction of your palm.
The force on the wire is directly proportional to the strength of the current. This means that the stronger the current, the greater the force exerted by the magnetic field on the wire.
The force on the wire can be negative if the direction of the current is opposite to the direction of the magnetic field. In this case, the force will act in the opposite direction to the force calculated using the formula F = BIL.
The force on the wire is directly proportional to the length of the wire. This means that the longer the wire, the greater the force exerted by the magnetic field. However, the force is also dependent on the current and the strength of the magnetic field, so a longer wire may not necessarily experience a stronger force if these factors are different.
