## Abstract

A magnetic stud sensor includes a handle portion and a body portion which together form an enclosure for loosely enclosing a magnet. The handle portion is adapted with indentations for a user's fingers and a projection for urging the magnet toward a wall. The body portion includes guides which, in connection with the projection, loosely hold the magnet near a planar portion of the body portion proximal a wall when the stud sensor is in use. As the stud sensor approaches a metal object behind a wall panel, the magnet is urged against and strikes the planar portion making an audible clicking or tapping sound.

## Claims

### Claim 1

A magnetic stud sensing device for sensing a wall stud comprising:
a handle portion adapted to be held in a user's hand;
a body portion having a planar portion adapted to engage a wall, and enclosing a magnet; and
an enclosure defined by the handle portion and body portion, wherein the enclosure is adapted to provide movement of the magnet.

### Claim 2 (depends on 1)

The magnetic stud sensor of claim 1 wherein the handle portion is circular.

### Claim 3 (depends on 1)

The magnetic stud sensor of claim 1 wherein the handle portion comprises indentations for a user's fingers.

### Claim 4 (depends on 1)

The magnetic stud sensor of claim 1 wherein the handle portion comprises a projection.

### Claim 5 (depends on 4)

The magnetic stud sensor of claim 4 wherein the projection is cylindrical.

### Claim 6 (depends on 1)

The magnetic stud sensor of claim 1 wherein the body portion comprises a smooth planar portion for engaging a wall.

### Claim 7 (depends on 6)

The magnetic stud sensor of claim 6 wherein the planar portion is slanted relative to the handle portion and body portion.

### Claim 8 (depends on 1)

The magnetic stud sensor of claim 1 wherein the body portion comprises guides adapted to loosely confine the magnet.

### Claim 9 (depends on 1)

The magnetic stud sensor of claim 1 wherein the handle portion and body portion comprise a mechanism for releasing the handle portion from the body portion. w

### Claim 10

A magnetic stud sensing device for sensing a wall stud comprising:
a handle portion having a circular hand grip, including indentations to accommodate a user's fingers and a projection extending from the hand grip;
a cylindrical body portion having an opening adapted to be covered by the handle portion, a planar portion adapted to engage a wall, and guides adapted for loosely enclosing a magnet; and
wherein the magnet is loosely bound by the guides and projection, such that when the magnet encounters a magnetic object, it strikes the planar portion, making an audible sound.
