A magnetic coil activator and a magnet for wheel steering control affects steering. A circuit applies a current to the coil thereby to move the magnet. Movement of the magnet is transmitted to a steering shaft thereby permitting steering the vehicle. The magnet is a permanent magnet, and includes a mounting to pivot the permanent magnet in relation to a coil, and wherein the coil is powered by the battery. The toy car can be remote controlled. ## Claims ### Claim 1 A movable toy vehicle comprising a vehicle body, chassis, a front wheel and a rear wheel, a power source with at least one battery, a magnetic coil activator and a magnet for wheel steering control, a circuit for applying a current to the coil thereby to move the magnet, and wherein movement of the magnet is transmitted to a steering shaft thereby permitting steering the vehicle. ### Claim 2 (depends on 1) A toy as claimed in claim 1, wherein the magnet is a permanent magnet, and including a mounting to pivot the permanent magnet in relation to the coil, and wherein the coil is powered by the battery. ### Claim 3 (depends on 1) A toy as claimed in claim 1, including a electronic circuit board for control of current to the coil, and a receiver with the vehicle for receiving a signal from a transmitter with the remote controller, the remote control having controls for a user to regulate the steering of the vehicle. ### Claim 4 (depends on 1) A toy as claimed in claim 1 including at least one drive electric motor for driving a wheel of the vehicle, a receiver with the vehicle for receiving a signal from a transmitter with the remote controller. a control of a drive motor, and for receiving remote signal from transmitter and a remote control device, the remote control having controls for a user to regulate the movement of the vehicle. ### Claim 5 (depends on 1) A toy as claimed in claim 1 including a mounting for the coil on the vehicle chassis, a permanent magnet attached to one end of a lever, and wherein the magnet is located inside the coil and pivotable transversely on the coil axis so the when the coil is energized by electric current, the magnetic field generated from the coil deflects the permanent magnet and the lever to one side. ### Claim 6 (depends on 5) A toy as claimed in claim 5 including providing the other end of the lever as a fork, and including a rod for engagement with the fork. ### Claim 7 (depends on 6) A toy as claimed in claim 6 including having the rod connect with a slide plate, the plate being slidable relative to a frame wherein when the lever is deflected by electromagnetic force, a plane movement of the slide plate is effected transversely of a longitudinal axis of the vehicle. ### Claim 8 (depends on 7) A toy as claimed in claim 7 wherein each respective end of the slide plate is connected to a mechanical linkage respectively of a left front wheel and a right front wheel for the vehicle. ### Claim 9 (depends on 8) A toy as claimed in claim 8 wherein when the slide plate performs a linear plane movement, the linear motion is transformed to a turning effect of front wheels of a vehicle. ### Claim 10 (depends on 8) A toy as claimed in claim 8 including a spring, the spring being for urging the return the slide plate and the lever to a neutral position, the neutral position being when the coil is dis-energized. ### Claim 11 (depends on 5) A toy as claimed in claim 5 including a ball joint on the other end of the lever, and including a rod for engagement with the ball joint. ### Claim 12 (depends on 1) A toy as claimed in claim 1 including mounting the coil relative to the chassis whereby the orientation of coil, and magnet is such that there is a vertical alignment of the coil. ### Claim 13 (depends on 1) A toy as claimed in claim 1 including mounting the coil relative to the chassis whereby the orientation of coil, and magnet is such that there is a horizontal alignment of the coil. ### Claim 14 (depends on 1) A toy as claimed in claim 1 including a pair of slide plate for performing a linear plane motion, and wherein the linear motion is transformed to a turning effect of front wheels of a vehicle, and wherein a first slide plate is mounted in front of a wheel axis and a second slide plate is mounted behind the wheel axis. ### Claim 15 (depends on 1) A toy as claimed in claim 1 including a front wheel suspension system, and a hinge relative to on the chassis, whereby the chassis and an axle between the front wheels are relatively movable and pivotable around a longitudinal axis of the vehicle. ### Claim 16 A movable toy vehicle and a remote control device having controls for a user to regulate the movement of the vehicle, the vehicle including a body, a chassis, a front wheel and a rear wheel, a power source with at least one battery, at least one drive electric motor for driving one of the wheels of the vehicle, an electronic circuit for controlling operation of the motor, a receiver with the vehicle for receiving a signal from a transmitter with the remote controller, a magnetic coil activator and a magnet for wheel steering control, a circuit for applying a current to the coil thereby to move the magnet, and wherein movement of the magnet is transmitted to a steering shaft thereby to effect turning of a wheel and for permitting steering the vehicle.
