Answer :
The formula for the force on current carrying wire in a magnetic field is given as
[tex]F=IlB\sin \theta[/tex]*Here I is the current
*Here l is the length
*Here B is the strength of the magnetic field
From the above expression, it is clear that the force on a current carrying wire in a magnetic field is proportional to the current, the length of wire in the field, and the field strength.
Therefore, the given statement is a true statement.
