CLAIMS

1 . A magnetic anchoring device providing a support on a wall structure comprising a magnetizable material, the magnetic anchoring device comprising:

a magnet unit configured to generate a magnetic field to develop an attracting force between the magnet unit and the wall structure;

a force generating device configured to engage the magnet unit, and to generate a test force in a predetermined direction between the magnet unit and the wall structure, the test force being adapted to test whether the magnet unit can withstand a required force during use without moving relative to the wall structure; and

a force measuring device connected to the force generating device, and configured for measuring the test force.

2. The magnetic anchoring device of claim 1 , wherein the force measuring device is configured to indicate whether the test force exceeds a predetermined level.

3. The magnetic anchoring device of claim 1 , wherein the force generating device is configured to generate a test force at right angles to a surface of the wall structure.

4. The magnetic anchoring device of claim 1 , wherein the force generating device is configured to generate a test force parallel to a surface of the wall structure.

5. The magnetic anchoring device of claim 3 or 4, wherein the force generating device comprises an electric, pneumatic or hydraulic actuator.

6. The magnetic anchoring device of any of claims 3-5, wherein the force generating device comprises a hydraulic piston/cylinder unit.

7. The magnetic anchoring device of claim 4, wherein the force generating device comprises a further magnet unit configured to generate a magnetic field to develop an attracting force between the further magnet unit and the wall structure.

8. A method of providing a support on a wall structure comprising a magnetizable material, the method comprising:

providing a magnet unit configured to generate a magnetic field;

providing the magnet unit on the wall structure to develop an attracting force between the magnet unit and the wall structure;

engaging the magnet unit by a test force in a predetermined direction between the magnet unit and the wall structure, the test force being adapted to test whether the magnet unit can withstand a required force during use without moving relative to the wall structure; measuring the test force;

if it is determined that the test force exceeds a predetermined value without the magnet unit moving relative to the wall structure, then removing the test force.
