Problem

An electromagnetic actuator must produce a force of at least

1.5\,\text{N}

. The available magnetic field in the device cannot exceed

0.40\,\text{T}

. The conductor will be kept perpendicular to the field. (a) If the current is limited to

10\,\text{A}

, determine the minimum length of conductor that must lie within the magnetic field. (b) The design allows only

30\,\text{cm}

of straight conductor to be placed in the field. State, with reason, whether the required force can be achieved under the given limits. a. If the current is limited to
